The relationship between volume and pressure (at constant temperature) is directly proportional.

my answer-
True

The relationship between pressure and temperature (at constant volume) is inversely proportional.

True

my answer-
False

No, no, yes.

Pressure and volume are inversely proportional. Pressure goes up, volume goes down.

Pressure and temperature are directly proportional. Temperature goes up, pressure goes up.

The last one is ok. Temperature goes up, volume goes up.

True

To understand the relationship between volume and pressure at constant temperature, we can refer to Boyle's Law. Boyle's Law states that the volume of a gas is inversely proportional to its pressure, as long as the temperature remains constant. In other words, if the volume decreases, the pressure increases, and vice versa.

To verify this relationship, one can perform an experiment called Boyle's Law experiment. In this experiment, a fixed amount of gas is confined in a container with a movable piston. By changing the position of the piston, the volume of the gas can be adjusted, while the temperature is kept constant. Gradually decreasing the volume will result in an increase in pressure, demonstrating the direct proportionality between volume and pressure at constant temperature.
