when temp increase,that mean average KE increase,if state change from solid to liquid or liquid to solid ,potential energy increase
For IDEAL GAS,it wont change to any state under HIGH TEMP LOW PRESSURE,so average KE increase but potential energy remains unchange
as far as we know,
INTERNAL ENERGY = AVERAGE KE + AVERAGE PE
SO,
THE ANS:A
for c,it is incorrect,because we didn't inject any gas ,so no of mole doesnt change and therefore no change in no of atoms
for d,change of internal energy, not equal to increase of volume of substance,please remember that internal energy is independent of the volume of the substance
What happens to the internal energy of an ideal gas when it is heated from 0C to 4C?
a. increases
b. decreases
c. change in number of atoms
d. increase in volume of substance
