A sample of ideal gas is in a sealed container. The pressure of the gas is 565 torr torr , and the temperature is 3 ∘C∘C . If the temperature changes to 69 ∘C∘C with no change in volume or amount of gas, what is the new pressure, P2P2P_2, of the gas inside the container

700 torr torr

Explanation:

Since the volume is constant

We use

P1/T1 = P2/V2

P1= 565torr torr, T1= 273+3= 276K, T2= 273+69= 342K

565/276 = P2/342

Simplify

P2= (565×342)/276 = 700.1 torr torr

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
