Which phrase correctly describes temperature? a. average rotational kinetic energy of the particles in an object b. average energy of the particles in an object c. average translational kinetic energy of the particles in an object d. all energy possessed by the particles in an object

At a given temperature, a system of particles can be considered as point masses (m) each moving at a certain translational velocity (v). The motion of these particles can be defined in terms of their average translational kinetic energy which is responsible for the heat transfer during molecular collisions and therefore the temperature of the system.

The kinetic temperature T is given in terms of the average translational kinetic energy as:

T  = 2/3k(Kinetic energy)

T = 2/3k(1/2*m*v²)

where K = Boltzmann constant

Ans: C) Average translational kinetic energy

C. Average translational kinetic energy of the particles in an object

Explanation:

Kinetic energy is the energy of motion and any moving object has kinetic energy because it’s moving.  Translational kinetic energy is a type of kinetic energy that is produced when an object has from moving from one location to another.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
