Answer:
The correct answer is B when the temperature is raised,volume is raised and C The piston moves up,decreasing the volume and increasing the pressure.
Step-by-step explanation:
According to Charles"s law in a fixed pressure constant mass of a gas"s volume is directly proportional to the temperature.Which means Volume of a gas increases with increase in temperature and volume of a gas decreases when temperature is lowered.
So the charles"s law fits the statement B when the temperature is raised volume is raised.
According to Boyle"s law in a fixed temperature constant mass of a gas"s volume is inversely proportional to pressure of that gas.Which means increase in volume occur by lowering the pressure and volume decreases when pressure increases.
So The Boyle"s law fits the statement C the piston moves u,decreasing the volume and increasing pressure.
