The temperature will stay the same
The temperature will be doubled
The temperature will be halved
The temperature will be quadrupled
The following equation can be used for interpolation:
Final Volume = Initial Volume + slope * change in temperature.
Therefore, at 350K, Volume = 1200 + 4*(350 − 300) = 1400 ml.
Experiment 1: Fill a balloon with one mole of hydrogen gas and another balloon with one mole of helium gas at constant temperature and measure the volumes of the two balloons.
Experiment 2: Fill a cylinder of fixed volume with hydrogen gas and another cylinder of fixed volume with helium gas at standard conditions of temperature and pressure and measure the weights of the gases in the two cylinders.
Experiment 3: Fill a balloon with one mole of hydrogen gas and another balloon with two moles of hydrogen gas at constant temperature and pressure and measure the volumes of the two balloons.
Experiment 4: Fill a 1 liter cylinder with hydrogen gas and a 2 liter cylinder with propane gas at room temperature and measure the mass of gas in each cylinder.
The temperature of the balloon will stay the same
The volume of the balloon will decrease
The volume of the balloon will increase
The temperature of the balloon will decrease
The volume will be doubled
The volume will stay the same
The volume will be halved
The effect on the volume cannot be determined
