What else can I help you with?
What happens when gas is heated?
it expands and/or its pressure rises, depending on conditions.
What happens to the volume of a gas when its temperature is raised and its pressure is cept constant?
Expands because there's more energy for movement.
What happens to a balloon when the gas in it increases?
It expands.
What happens to a gas when it expands?
The behaviour of gas particles are completely different because they randomly move within provided space. For them to expand, we can increase the pressure or either increase the temperature slightly.
What happens when air heated?
It expands, taking up more space, if there is no more space, pressure in the container increases.
Why a gas cools when it expands at high pressure?
When a gas expands at high pressure, it does work on its surroundings to overcome the external pressure. This work done by the gas results in a decrease in its internal energy, leading to a decrease in temperature as per the first law of thermodynamics. So, the gas cools down as it expands at high pressure.
What happens to the internal energy of a gas when it expands?
When a gas expands, its internal energy typically increases. This is because the gas is doing work on its surroundings as it expands, which results in an increase in its internal energy.
What happens to air as it expands?
As air expands, it cools down due to a decrease in pressure. This cooling effect is due to the gas molecules moving further apart and losing energy. Consequently, the temperature of the air decreases as it expands.
What is a gas that expands when heated?
Any gas will expand when heated, assuming you keep pressure constant.
What will happen to pressure when gas expands and volume increases?
When a gas expands and its volume increases, the pressure of the gas will decrease. This is because pressure and volume are inversely proportional according to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature.
When a gas expands isobarically the product of the pressure and change of volume is equal to which one of these statements?
When a gas expands isobarically (at constant pressure), the product of the pressure and the change in volume is equal to the work done by the gas during the expansion. Mathematically, this can be expressed as ( W = P \Delta V ), where ( W ) is the work done, ( P ) is the constant pressure, and ( \Delta V ) is the change in volume. This work is positive when the gas expands, indicating that energy is transferred from the gas to its surroundings.
What determines how far gas expands?
The initial pressure, temperature, and volume of the gas will determine how far it expands. When heated or when pressure is reduced, gas molecules move faster and spread out over a larger area, causing the gas to expand.
