Which law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions? Boyle's law Charles's law Dalton's law Gay-Lussac's law
Gay-Lussac's law
The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the pressure of the gas? It decreases by a factor of four. It increases by a factor of four. It decreases by a factor of eight. It increases by a factor of eight.
It increases by a factor of four.
Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions? Boyle's law Charles's law Dalton's law Gay-Lussac's law
charles' Law
If two gases are present in a container, the total pressure in the container is equal to the sum of the pressures that are exerted by each of the two gases. twice the sum of the pressures that are exerted by the individual gases. the sum of the pressures that each gas would exert if they occupied twice the volume. the sum of the pressures that each gas would exert if they occupied half the volume.
the sum of the pressures that are exerted by each of the two gases.
