2. One mole of a monatomic ideal gas undergoes a reversible expansion at constant pressure, during which the entropy of the gas increases by 14.41 J/K and the gas absorbs 6236 J of thermal energy. Calculate the initial and final temperatures of the gas.

The initial and final temperatures of the gas is 300 K and 600 K.

Explanation:

Given that,

Entropy of the gas = 14.41 J/K

Absorb gas = 6236 J

We know that,

At constant pressure,

Put the value into the formula

...(I)

We need to calculate the initial and final temperatures of the gas

Using formula of energy

Put the value into the formula

Put the value of T₂

Put the value of T₁ in equation (I)

Hence, The initial and final temperatures of the gas is 300 K and 600 K.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
