Question

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.

Answer 1

Apartment Explosion Reported

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

When heat is provided then temperature increases and the molecules of substances move rapidly by increase of kinetic energy (K.E) temperature increases. It is understood that heat increases temperature.

Answer 2

Answer: 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
