A gas sample enclosed in a rigid metal container at room temperature (20.0∘C) has an absolute pressure p1. The container is imme
Vlad [161]

Answer : The new absolute pressure is, 1.068\times P_1

Explanation :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T

or,

\frac{P_2}{P_1}=\frac{T_2}{T_1}

where,

P_1 = initial pressure of gas

P_2 = final pressure of gas

T_1 = initial temperature of gas = 20.0^oC=273+20.0=293.0K

T_2 = final temperature of gas = 40.0^oC=273+40.0=313.0K

Now put all the given values in the above equation, we get:

\frac{P_2}{P_1}=\frac{313.0K}{293.0K}

\frac{P_2}{P_1}=1.068

P_2=1.068\times P_1

Therefore, the new absolute pressure is, 1.068\times P_1

Two glasses of water have the same thermal energy. Must they have the same temperature? Explain
ira [324]
Even if two samples of matter have the same temperature, it does not necessarily mean they have the same total energy. The more particles a substance has at a given temperature, the more thermal energy it has.
