how many kPa are in 2,150 mmHg

287 kPa

a gas has a temperature of 273.15 K and a pressure of 101.325 kPa. what can be concluded about the gas

it has reached standard temperature and pressure

which best defines partial pressure in a mixture of gases

pressure that is exerted by one gas as if it occupied a container by itself

which change would increase the pressure exerted by a gas

raising the temperature of the gas

the volume of a gas is 450 mL when its pressure is 1.00 atm. if the temperature of the gas does not change, what is the pressure when its volume changed 2.00 L

0.225 atm

a scientist is examining a mixture of nitrogen, hydrogen, and ammonia. the individual pressures that are exerted by nitrogen and hydrogen are 0.26 atm and 0.28 atm, respectively. if the total pressure is 0.90 atm, what is the partial pressure of ammonia

0.36 atm

what is the volume of 0.200 mol of an ideal gas at 200. kPa and 400. K

3.33 L

which proportionality shows the result of combining avogadro's law with boyle's law

V x n/P

which law is described by saying that when the pressure of a gas in a sealed container is cut in half, the gas will double in volume at a steady temperature

boyle's law

which sequence describes the result of increasing the temperature of a gas in a container

higher kinetic energy < greater collision force < higher pressure

the volume of a gas decreases to half of its original volume, but the gas maintains the same number of moles and temperature. according to the ideal gas law, what will most likely happen to the pressure

it will double

if a gas is moved from a large container to a small container but its temperature and number of moles remain the same, what would happen to the pressure of the gas

it would increase

which units of pressure are equivalent and require no conversion of the value

mmHg and torr

the ideal gas constant, R has seeral different values that could be used. which quantity causes these differences

pressure

if the pressure, volume, and temperature of a gas are known, which can most likely be found by using the ideal gas law

the molar amount of the gas

which describes the volume of 1 mol of gas at standard temperature and pressure

the volume is the same for any gas
