At a temperature of 280k, the gas in a cylinder has a volume of 20.0 liters.

if the volume of the gas is decreased to 10.0 liters, what must the temperature be for the gas to remain at a constant pressure?

T = 140 K

Explanation:

As we know by ideal gas law

now if pressure of the gas is constant

then we will have

now we have

now from above equation

so easy. just google the electromagnetic waves and it’ll pop up.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
