When a gas is heated at a constant rate, the volume will also increase at a constant rate.
When heated, temperature increases. You may have already guessed that. Most substances, but not all, increase in volume as the temperature increases at constant pressure. The pressure would remain the same if the fluid was in an open container.
The pressure is higher.
Regarding only gases for the moment ... If the gas is heated while its volume remains constant, then its pressure increases.
In an adiabatic process when pressure remains constant but volume is decreased, temperature will increase. If pressure remains constant but volume increases, temperature will decrease
If the volume is tripled, then the volume becomes three times as great, regardless of what happens to either the temperature or the pressure.
Temperature will be increase
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
If the temperature of the gas is decreasing, then in order to maintain constant pressure, you would have to compress it in volume.
At constant volume, its pressure will vary proportionally with its absolute temperature change.
If the temperature is held constant the pressure of a gas will increase if the volume decreases.
Read your question ... you state that the volume remains constant.
The pressure increases.
When the Temperature increases, so does the Pressure.
Assuming temperature is held constant, the volume is reduced by half.
Temperature would decrease . ( Temperature is directly proportional to pressure if volume is constant )
If pressure is held constant, volume and temperature are directly proportional. That is, as long as pressure is constant, if volume goes up so does temperature, if temperature goes down so does volume. This follows the model V1/T1=V2/T2, with V1 as initial volume, T1 as initial temperature, V2 as final volume, and T2 as final temperature.
Its pressure decreases.
That depends on what the system is being subjected to... If work is done on a system at constant volume, the temperature would be expected to increase. If heat is transferred out of a system at constant volume, the temperature it expected to increase. Chemical changes in a system may increase or decrease the temperature depending on what change occurs. Phase changes can occur at constant volume with no change in the temperature at all.
If pressure remains constant, then volume is directly proportional to temperature. Hot air is quite loud.
the pressure is reduced by 1/2
