The volume of a gas is 400.0 mL at 30.0°C. If the temperature is increased to 50.0°C without changing the pressure, what is the new volume of the gas?

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?

A40 kilogram skier starts at the top of a 12 meter high slope. at the bottom, she is travelling 10 meters per second. how much energy does she lose to friction

Charles's law describes the relationship of the volume and temperature of gas at a constant mass and pressure. according to this law, what would happen to the temperature of the gas if its volume decreased from 1.0 l to 0.50 l?
