The volume of a gas decreases to half of its original volume, but the gas maintains the same number of moles and temperature. according to the ideal gas law, what will most likely happen to the pressure?

Pressure will be doubled if volume of gas decreases to half of its original volume

Explanation:

Ideal gas law:

where, P is pressure, V is volume, n is number of moles, R is gas constant and T is temperature in kelvin scale.

Here n and T are constants. Also R is a constant,

Hence we can write,

where, and are initial and final pressure respectively. and are initial and final volume respectively.

Here,

So,

or,

So, pressure will be doubled if volume of gas decreases to half of its original volume
