I found the answer sheet online for you
Answer:
Explanation:
The word "sheet" implies that the copper is quite thin.
Copper is also a very good conductor of heat.
Therefore, with a very short heat flow distance to cover and a high rate of heat transmission, temperature differences on either side of the sheet are almost instantaneously eliminated by heat flow.
Answer:
The new volume of the ballon will be 13.345 L
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.
Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
It is possible to assume that you have a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the temperature will change to T2, and it will be true:
In this case:
- V1= 17 L
- T1= 200 K
- V2= ?
- T2= 157 K
Replacing:
Solving:
V2= 13.345 L

Answer:
(a) 918.37 kg
(b) 2020.41 lbs
Explanation:
number of students = 20
Force of each student = 450 N
Total upward force = 450 x 20 = 9000 N
(a)
Let m be the mass of car
F = m x g
9000 = m x 9.8
m = 918.37 kg
(b)
As we know that, 1 kg = 2.20 lbs
So, 918.37 kg = 2.20 x 918.37 = 2020.41 lbs
