Answer:
B. how fast the particles are moving
Step-by-step explanation:
Temperature measures the average kinetic energy of system as result of the thermal - heat energy present in the reaction or a body.
Often times, temperature is the degree of hotness or coldness of a body and this translates to an increase or decrease in the molecular speed.
- Number of particles in a body is the mass of the body.
- How tightly packed the particles are corresponds to the density of the body.
