According to KE = (3/2)kT
reducing temperature, in KELVIN, by half, average KE is reduced by half.
Answer:
The temperature of air will increase by 
Explanation:
Given:
- no. of person in a theater,

- volume of air in the theater,

- rate of heat given off by each person,

- duration of movie,

- initial pressure in the theater,

- initial temperature in the theater,

- specific heat capacity of air at the given conditions,

<u>The total quantity of heat released by the total people in the theater during the movie:</u>



<u>Form the relation of heat capacity:</u>

∵



Change in temperature of air:

Sound waves are a type of classical waves and so they transport only energy without transporting matter through the medium.
Answer:
Because work can be defined as force time distance, we can also use the following equation
Solution
P=power (w or ft-lbf/s)
F=force (N or lbf)
D=distance (m or ft)
T=time (sec)
One horsepower is equivalent to 550 ft-lbf/s and 745.7 watts.
