Afixed amount of gas at 25.0°c occupies a volume of 10.0 l when the pressure is 751 torr. use boyle's law to calculate the pressure (torr) when the volume is reduced to 9.25 l at a constant temperature of 25.0°c.

811.89 torr

Explanation:

According to Boyle's Law ,

At a constant temperature , Product of Pressure and volume of the gas remains constant for a fixed Amount of gas.

Thus,

=  

Here,

= 751 torr

= 10.0L

= 9.25 L

Thus,

751×10 = 9.25×

= 811.89 torr.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
