TEMPERATURA E CALORE

  1. Completa le frasi scegliendo la parola corretta: 

CALORE – DILATAZIONE – AGITAZIONE – PASSAGGI DI STATO – TERMOMETRO – MAGGIORE

  1. La temperatura dipende dall’......................... delle particelle e si misura con il .........................
  2. La ......................... è l'aumento delle dimensioni di un corpo quando viene scaldato.
  3. Il ......................... è l'energia che passa da un corpo con temperatura ......................... a uno con temperatura minore.
  4. I ......................... avvengono quando una sostanza cambia il suo stato di aggregazione.

2) Collega ogni termine alla sua definizione corretta.

  1. conduzione …… il calore si sposta anche nel vuoto, senza contatto
  2. convezione …… il calore si trasmette tra corpi solidi posti a contatto
  3. irraggiamento …… il calore si trasferisce per spostamento di materia

3) Collega ogni termine all’esempio pratico.

  1. conduzione …… l'aria calda dei termosifoni che sale verso l'alto.
  2. convezione …… il calore del Sole che arriva sulla Terra.
  3. irraggiamento …… un cucchiaio di metallo che scotta dentro il brodo.

4) Leggi l'esempio e scrivi accanto il nome del passaggio corretto. Scegli tra: FUSIONE – EVAPORAZIONE – SOLIDIFICAZIONE – CONDENSAZIONE – BRINAMENTO – SUBLIMAZIONE.

5) Completa lo schema dei passaggi di stato con:

Image removed.

6) Laboratorio 1: quantità di sostanza, temperatura e calore.

Ricorda l’esperimento: abbiamo scaldato un becher con 100 ml e uno con 200 ml d'acqua sulla stessa fiamma per lo stesso tempo.

A) Scegli l'osservazione corretta (segna con una X):

  • Image removed.L'acqua nel becher da 200 ml ha raggiunto una temperatura più alta.
  • Image removed.L'acqua nel becher da 100 ml ha raggiunto una temperatura più alta.
  • Image removed.Entrambi i becher hanno raggiunto la stessa identica temperatura. 

B) Perché è successo questo? 

........................................................................................................................................................................................................................................................................................................................................................................................................................................................

7) Laboratorio 2: dilatazione termica.

Ricorda gli esperimenti: la sfera di metallo scaldata sulla fiamma e il palloncino sulla beuta scaldata.

A) Cosa hai osservato durante le prove? 

  • Image removed.La sfera scaldata passa ancora meglio nell’anello e il palloncino non si è mosso.
  • Image removed.Non è cambiato nulla: la sfera è uguale e il palloncino non si è mosso.
  • Image removed.La sfera scaldata non passa più nell’anello e il palloncino si è gonfiato.

B) Perché succede questo? 

........................................................................................................................................................................................................................................................................................................................................................................................................................................................

8) Laboratorio 3: evaporazione ed ebollizione.

Ricorda l’esperimento: abbiamo scaldato l’acqua misurando la temperatura ogni 2 minuti con il termometro fino a farla bollire.

  • Image removed.la temperatura sale fino a che si raggiunge l’ebollizione e poi resta costante
  • Image removed.la temperatura continua a salire anche quando l’acqua bolle
  • Image removed.la temperatura sale fino a che si raggiunge l’ebollizione e poi scende

B) Perché succede questo? 

........................................................................................................................................................................................................................................................................................................................................................................................................................................................Image removed.

C) Specifica nel grafico qual è la parte relativa all’evaporazione e quella relativa all’ebollizione.



 

9) Il termometro e la scala centigrada. 

 A) Completa le frasi indicando a quale fenomeno corrispondono i numeri:

Nella scala centigrada:

  • lo 0 °C corrisponde alla temperatura di: ...........................................
  • i 100 °C corrispondono alla temperatura di: ........................................

B) Cos'è un "grado centigrado"? 

  • Image removed.La distanza totale tra lo zero e i cento gradi.
  • Image removed.Ognuna delle 100 parti uguali in cui è divisa la scala tra fusione ed ebollizione.
  • Image removed.La temperatura massima che si può misurare con un termometro.

10) Lo strumento: il termometro a liquido.

A) Completa la descrizione dello strumento usando le parole: CAPILLARE – LIQUIDO – BULBO - VOLUME.

Il termometro è composto da un piccolo serbatoio chiamato ........................... che contiene un ............................ Quando la temperatura sale, il liquido aumenta di ........................... e scorre dentro un tubicino molto sottile chiamato ...........................

B) Perché il liquido sale nel tubicino quando viene scaldato?

..........................................................................................................................................................................................................................................................................................................................................

11) Un caso speciale: l’anomalia dell’acqua.

A) Cosa succede all'acqua quando viene scaldata da 0°C a 4°C? 

  • Image removed.Si dilata come tutti gli altri liquidi.
  • Image removed.Invece di dilatarsi, il suo volume diminuisce (si restringe).
