Arigid container holds a gas at a pressure of 55 kpa and a temperature of -100.0*c. what will the pressure be when the temperature is increased to 200*c

P2 = 150.4 KPa

Explanation:

Gay-Lussac's Law:

at constant volume, the pressure of a gas varies directly with the temperature

∴ P1 = 55 KPa

∴ T1 = - 100.0°C ≅ 173 K

∴ T2 = 200°C ≅ 473 K

⇒ P2 = ?

⇒ P2 = (473 K)(55 KPa) / (173 K)

⇒ P2 = 150.4 KPa

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.
