A sample of gas occupies 324 mL at 40.0°C. What volume will the gas occupy at
20.0°C if there is no change in pressure?

303 ml

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

where,

are the initial volume and temperature of the gas.

are the final volume and temperature of the gas.

We are given:

Putting values in above equation, we get:

Thus volume of the gas at 20.0°C if there is no change in pressure is 303 ml

dishwashers don't have rights

explanation:

dishwashers are meant for one thing and one thing only: dishwashing. they belong in the kitchen making sandwiches and cleaning up for the man of their household. if your dishwasher starts acting up just slap it and wait a minute.
