Answer:
The average kinetic energy of the molecules in the system
Explanation:
According to the kinetic theory of matter, the particles of a system are in constant motion and collide steadily with one another as well as with the walls of the container.
The average kinetic energy of these molecules in motion is referred to as the temperature of the body. Hence, temperature is a measure of the average kinetic energy of the molecules of a body.
The new volume of air trapper in the cylinder is determined as 116.56 mL.
<h3>
New volume of air in the cylinder</h3>
The volume of air trapper in the cylinder is determined from Boyle's law;
P₁V₁ = P₂V₂
where;
- P₁ is initial pressure = 1.08 atm
- V₁ is initial volume = 145.7 mL
- P₂ is new pressure = 1.25 x 1.08 atm = 1.35 atm
- V₂ is new volume = ?
V₂ = (P₁V₁)/P₂
V₂ = (1.08 x 145.7)/1.35
V₂ = 116.56 mL
Thus, the new volume of air trapper in the cylinder is determined as 116.56 mL.

Answer: 2116.8 seconds
Explanation:
0.0035 weeks × 7days/week × 24hrs/day × 60min/hr × 60sec/min
=2116.8 seconds
=2100 (if you are required to consider significant figures)
