Other things being equal - yes. Less speed means less temperature.

Does the volume of a gas always increase when temperature increases and pressure decreases?
Yes. When the temperature increases the molecules are more excited and move farther apart. When the pressure decreases, the molecules also have more space and will fill the void.
How does speed affect Power?
Speed is directly related to power. As speed increases, power also increases. And as speed decreases, power also decreases.
The pressure of gas decreases with increasing temperature?
If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.
How does the speed of the molecules of a gas change when heated?
it moves faster
How the temperature of gas is increased and decreased?
When the speed of a gas molecules increases, the gas molecules hit their container more often. The more frequently the gas impacts the container walls, the higher the pressure. So, as temperature increases, the pressure also increases.
What happens to the pressure of a gas inside a contianer ifthe temperature of the gas decreases?
from the gas laws and Charles 2nd law, it can be concluded that pressure is directly proportional to temperature..hence if the temp decreases; pressure also decreases as the kinetic energy of the molecules decreases; the collisions decrease hence pressure of the molecules inside the container decrease.
Does the volume of a gas always increase when temperature increases and pressure decreases?
Yes. When the temperature increases the molecules are more excited and move farther apart. When the pressure decreases, the molecules also have more space and will fill the void.
As the density of air decreases its pressure what?
Temperature is always measured when surface have transition from hot to cold or vice-versa. When molecules decrease in density, implies the individual molecules get cooler/hotter faster to room temp.hence,When air molecules decrease air temperature rapidly changes to room temperature or ambient temperature.
How does the gas volume vary with change in pressure?
This one is explained in Boyle's Law. It was stated that if the temperature is constant, the pressure is inversely proportional to the volume. Thus, if the pressure increases, the volume decreases. It is also the same as if the pressure decreases, the volume of the gas increases.
How does speed affect Power?
Speed is directly related to power. As speed increases, power also increases. And as speed decreases, power also decreases.
Why do you think more pressure on a gas causes the volume of the gas to decrease?
Increased pressure causes the gas molecules to come closer together, thus the volume also decreases.
Why does a balloon get smaller in cold weather?
The simple answer is because the pressure remains the same. When pressure remains constant, the change in volume will be directly proportional to the change in temperature. The air molecules release energy as they travel around inside the balloon. What we call pressure is technically the force of the air molecules colliding with the inside of the balloon and each other. The kinetic energy is related to the speed of the molecules. The faster the molecules are moving, the greater the kinetic energy. The greater the kinetic energy, the greater the pressure in the inside of the balloon. The outside air is doing the same thing to outside of the balloon. Therefore, the pressure pushing out is equal to the pressure pushing in. Temperature decreases because the molecules inside the balloon are releasing their energy in the form of heat as they interact with each other. In fact, they heat energy passes through the balloon and is absorbed by the air on the outside. Over time, more energy is released, and the temperature drops. The volume of the balloon decreases in order to maintain a constant pressure. As the surface area decreases, the total pressure pushing in also decreases so that it always equals the pressure pushing out.
How do you explain the increase in pressure in a closed system when temperature is increased?
Since the temperature is increased, the molecules start moving to and fro... which tends increase in speed of the molecule.. such that the increase in temperature is directly proportional to the speed of the molecules by which the pressure will also increase...
When the temperature of a gas decreases it's?
The volume it occupies also decreases. The pressure it exerts also decreases. The rate at which it will react with other substances also decreases.
The pressure of gas decreases with increasing temperature?
If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.
How does the speed of the molecules of a gas change when heated?
it moves faster
Why does pressure decrease but temperature varies as altitude increases?
there is less oxygen and the molecules are more spread out
