What else can I help you with?
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
If the temperature is increased, the partial pressure of oxygen in a sample of air will also increase. This is because as the temperature rises, the oxygen molecules in the air will have greater kinetic energy and will exert more pressure.
What sample is highly compressible at high pressure and expandable at high temperature?
liquid
What happens to a fixed sample of gas when its temperature changes?
When the temperature of a fixed sample of gas changes, its particles will gain or lose kinetic energy, leading to a change in their speed and collisions. This results in a change in pressure and volume of the gas, according to the ideal gas law.
When a fixed sample of gas increases in volume what happens to the pressure and temperature?
The frequency of collisions is reduced
What is sublimation and give an example of a substance that sublimes?
If zinc chloride is heated strongly the solid will sublime.
What sample of matter sublimes at room temperature and standard pressure?
Dry ice (solid carbon dioxide) sublimes at room temperature and standard pressure, meaning it changes directly from a solid to a gas without passing through the liquid phase.
What does the state of a sample of matter depend on?
The state of a sample of matter (solid, liquid, gas) depends on its temperature and pressure. When temperature increases, matter transitions from solid to liquid to gas. Pressure can also influence these transitions, such as changing the point at which a substance boils or freezes.
What happens to the partial pressure of oxygen in a sample of air when the temperature increases?
When the temperature of a sample of air increases, the partial pressure of oxygen also increases.
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
If the temperature is increased, the partial pressure of oxygen in a sample of air will also increase. This is because as the temperature rises, the oxygen molecules in the air will have greater kinetic energy and will exert more pressure.
Which sample of water has the lowest vapor pressure?
The sample of water that has the lowest vapor pressure is the sample at a lower temperature. Vapor pressure decreases as temperature decreases because fewer molecules have enough energy to escape into the gas phase.
Which property is a measure of the average kinetic energy of the particles in a sample of matter?
Temperature is the correct answer because temperature measures average kinetic energy.
A measure of the average kinetic energy of the particals in a sample of matter?
temperature
What is a Uniform temperature?
The temperature is the same no matter where you test the sample. There is no region that is hotter or cooler than another.
What sample is highly compressible at high pressure and expandable at high temperature?
liquid
What happens to a fixed sample of gas when its temperature changes?
When the temperature of a fixed sample of gas changes, its particles will gain or lose kinetic energy, leading to a change in their speed and collisions. This results in a change in pressure and volume of the gas, according to the ideal gas law.
What term is defined as a measure of the average kinetic energy of the particles in a sample of matter?
Temperature is defined as a measure of the average kinetic energy of the particles in a sample of matter. It indicates how hot or cold an object is.
What is the average speed of gas molecules in a given sample at a specific temperature and pressure?
The average speed of gas molecules in a sample at a certain temperature and pressure is determined by the kinetic theory of gases. This speed is directly proportional to the square root of the temperature and inversely proportional to the square root of the molecular weight of the gas.
