The apartment’s explosion, reportedly caused by a gas leak, produced a violent release of gas and heat. the heat increased the of the air in the room, which means an increase in the air's molecular kinetic energy.

Temperature or Pressure

Explanation:

We need to complete the next:

"The apartment’s explosion, reportedly caused by a gas leak, produced a violent release of gas and heat. the heat increased the of the air in the room, which means an increase in the air's molecular kinetic energy."

We can suppose the air as an ideal gas, which is defined by the equation:

PV = nRT

where P is pressure, V is volume and T is temperature (n, the number of particles, and R are constants)

Here, if the temperature of the air, T, increases, then the product PV must also increase.

This means that the volume and pressure increases (first increases the volume, until the walls don't let ani more expansion, in this point the pressure starts to increase) In this case the volume is fixed (is the volume of the apartment) so the only things that can change are the pressure and the temperature.

This expansion is the "wave" created by the explosion and is the "destructive" part of the explosion.

The word that best can complete the statement is Pressure, but Temperature

it is the second option.

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
