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
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
Well, when an ideal gas is heated from 0C to 4C, the internal energy of the gas increases. It's like giving the gas a warm hug and boosting its energy levels. So, the answer is a. increases. Just like when you have a cup of coffee, it gets hotter and you also feel more energized!
The internal energy of an ideal gas is directly related to its temperature. According to the ideal gas law, as the temperature of a gas increases, its internal energy also increases. Therefore, the correct answer is a. increases.
To determine what happens to the internal energy of an ideal gas when it is heated from 0°C to 4°C, we need to understand the relationship between temperature and internal energy.
Firstly, let's clarify that internal energy refers to the total energy possessed by the particles (atoms or molecules) within a substance. It includes the kinetic energy of the particles (related to their motion) and the potential energy between them.
In an ideal gas, assuming that the gas behaves ideally and there are no intermolecular forces, the internal energy only depends on the temperature and is independent of other factors such as volume or the number of atoms.
According to the ideal gas law, the temperature of an ideal gas is directly proportional to its internal energy. When the temperature of an ideal gas increases, the internal energy also increases. Conversely, when the temperature decreases, the internal energy decreases.
Therefore, when the ideal gas is heated from 0°C to 4°C, the correct answer is (a) the internal energy of the ideal gas increases.
