Answer 1

$\huge{\mathtt{\underline{\blue{Answer}}}}$

According to Charles law, for a fixed mass of the gas at constant pressure the volume of the gas is proportional to the temperature. Kinetic theory explains why the volume of the container should increase with the increase in the temperature to keep the pressure constant. When the temperature is increased, the kinetic energy of the molecules increases. This increases the rate of collision and causes an increase in pressure. If the dimension of the container is increased the molecules will move a larger distance before collision. This maintains the rate of collision and keeps the pressure constant.
