What must happen to a fixed sample of a gas when its temperature changes?
Explain what happens to a fixed sample of gas when its temperature changes. For a fixed amount of gas at a constant temperature, the volume of a gas increases as the gas’s pressure decreases. Likewise, the volume of a gas decreases as the gas’s pressure increases.
What happens to gas when the temperature changes?
The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. They strike the surface of the container with more force. If the container can expand, then the volume increases until the pressure returns to its original value.
What happens to a sample of gas when it experiences an increase in temperature?
When you heat a gas, both its vapor pressure and the volume it occupies increase. The individual gas particles become more energetic and the temperature of the gas increases. At high temperatures, the gas turns into a plasma.
What happens to gas molecules when temperature decreases?
As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down.
When a fixed sample of gas increases in temperature it must also?

What is the process when solid changes to gas?
sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature.
When a fixed sample of gas increases in volume it must also what?
The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle’s law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.
When a sample of gas increases in volume it must also?
FIGURE 9.8 Boyle’s Law: At constant temperature, the volume of a gas sample is inversely proportional to the pressure. The curve is a graph based on the data listed in the figure….C. The Combined Gas Law.
