What is the formula for calculating the change in pressure when the volume and temperature of a gas are held constant?
The formula for calculating the change in pressure when the volume and temperature of a gas are held constant is: P (nRT/V)T, where P is the change in pressure, n is the number of moles of gas, R is the gas constant, T is the temperature, V is the volume, and T is the change in temperature.
What happends to the speed of a wave if the medium and temperature and pressure do not change?
The speed of a wave remains constant if the medium, temperature, and pressure do not change. This is because the speed of a wave is determined by the properties of the medium through which it is traveling, and as long as those properties remain constant, the speed will also remain constant.
What variable is held constant in Boyle's law?
Boyle's Law states that in for an ideal gas, a change in pressure is directly related to a change in volume. From the Ideal Gas Law, PV=nRT, we can see that there are four factors to consider when making calculations involving ideal gases, pressure, volume, temperature, and mols of gas involved. Since we're testing Boyle's Law, pressure and volume must be changing, so temperature and mols of gas involved must be constant.
What ideal gas is stored in a container at constant volume. If the temperature (T) were increased to 3T what would be the change in pressure (P)?
The ideal gas law states that pressure (P) is directly proportional to temperature (T) at constant volume. So if the temperature is increased to 3T, the pressure would also increase by a factor of 3.
What is the relationship between temperature change and the heat capacity at constant pressure?
The relationship between temperature change and heat capacity at constant pressure is that as the temperature increases, the heat capacity also increases. Heat capacity is a measure of how much heat energy is needed to raise the temperature of a substance by a certain amount, and it tends to increase with temperature because the substance can absorb more heat energy as it gets hotter.
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
Does sound velocity change based upon sound frequency?
No, sound velocity does not change based on sound frequency in a uniform medium. In a medium with a constant temperature and pressure, the speed of sound remains constant regardless of the frequency of the sound waves.
What is the formula for calculating the change in pressure when the volume and temperature of a gas are held constant?
The formula for calculating the change in pressure when the volume and temperature of a gas are held constant is: P (nRT/V)T, where P is the change in pressure, n is the number of moles of gas, R is the gas constant, T is the temperature, V is the volume, and T is the change in temperature.
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
How is isothermal possible in a balloon?
Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
Pressure and volume change at a constant temperature who's law is this?
Boyles Law
What happens to the speed of a wave of the medium temperature and pressure do not change?
remains constant
When scientists record the volume on a gas why do they also record the temperature and the pressure?
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
How does volume of matter change with increase in temperature?
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
What happends to the speed of a wave if the medium and temperature and pressure do not change?
The speed of a wave remains constant if the medium, temperature, and pressure do not change. This is because the speed of a wave is determined by the properties of the medium through which it is traveling, and as long as those properties remain constant, the speed will also remain constant.
