Agas‑filled weather balloon has a volume of 50.0 l at ground level, where the pressure is 759 mmhg and the temperature is 22.3 ∘ c. after being released, the balloon rises to an altitude where the temperature is − 9.00 ∘ c and the pressure is 0.0701 atm. what is the weather balloon's volume at the higher altitude?

The volume of balloon at higher altitude is 631.3 L

Explanation:

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law. The equation follows:

where,

are the initial pressure, volume and temperature of the gas

are the final pressure, volume and temperature of the gas

We are given:

Conversion factor:  1 atm = 760 mmHg

Putting values in above equation, we get:

Hence, the volume of balloon at higher altitude is 631.3 L

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
