Q

Hvad er varmekapacitet?

A

C = hvor meget varmeenergi der kræves for at ændre temperaturen af et materiale.

18
Q

Hvad er specifik varmekapacitet?

A

c = mængden af varmenergi som kræves, for at ændre et materiales temperatur med én grad.

19
Q

Hvad er specifik smeltevarm?

A

L_s = mængden af varmeenergi, som kræves for at smelte en genstand (og dermed ændre fase fra fast til flydende).

20
Q

Hvad er specifik fordampningsvarme?

A

L_f = mængden af varmeenergi, som kræves for at smelte en genstand (og dermed ændre fase fra flydende til fast).
