According to the ideal gas law, pressure times volume is constant. We'll call that constant c. PV=C, P=c/V, so pressure is inversely related to volume, so it would look like the graph y=1/x multiplied by a constant.

pressure and volume

I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)

False. According to Charles's Law, when the temperature of a gas is decreased at constant pressure, the volume of the gas will also decrease. This is because at lower temperatures, the gas molecules have less kinetic energy and move more slowly, occupying less space.

Charles' Law states that there is a direct mathematical relationship between volume and temperature of a gas.

When the volume of a gas decreases at constant temperature according to Boyle's Law, the pressure of the gas increases. This relationship is represented by the formula P1V1 = P2V2, indicating that as the volume decreases, the pressure must increase to maintain the product of pressure and volume constant.

When the volume of a confined gas is reduced by half at a constant temperature, the pressure of the gas will double according to Boyle's Law. This is because the product of pressure and volume is constant for a given amount of gas at constant temperature. When the volume decreases, the pressure increases to maintain this equilibrium.

If the volume of a gas is tripled at constant temperature, according to Boyle's Law, the pressure of the gas will decrease by a factor of 3. This is because pressure and volume are inversely proportional at constant temperature.

they also become constant.

The volume of the gas must remain constant for pressure and temperature to be directly proportional, according to Boyle's Law. This means that as the pressure of a gas increases, its temperature will also increase proportionally, as long as the volume is held constant.

The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.

According to Boyle's Law, as the volume of a gas decreases, the pressure increases, and vice versa. This is because the relationship between pressure and volume is inversely proportional when the temperature is held constant.

According to Boyle's law, pressure and volume are inversely related at a constant temperature. This means that as the volume of a gas decreases, the pressure increases proportionally, and vice versa. Mathematically, this relationship is represented by the equation P1V1 = P2V2, where P represents pressure and V represents volume.

No, it is not possible for the balloon to naturally expand four times its initial volume while the temperature remains constant. According to Boyle's Law, at constant temperature, the pressure and volume of a gas are inversely proportional. Since the atmospheric pressure remains constant, the balloon's pressure of 200.0kPa would need to increase to expand, which cannot happen at constant temperature.
