Question 1

In this experiment, we will measure the heat loss of an object and heat gain of another during a heat exchange process. The heat loss and heat gain are supposed to be equal to each other. However, your measurement find that the heat loss is 1.27 J while the heat gain 1.56 J.What is the percent difference of the two values?

Question 2

Question 3

The heat capacity defines the heat stored in an object at a certain time.

True

False

Question 4

Object A and C are in thermal equilibrium; Object B and C are in thermal equilibrium as well. Then object A and B must also be in thermal equilibrium.

True

False

Question 5

What is the SI unit for temperature?

Fahrenheit

Celsius

Kelvin

Question 6

How much heat in kJ is needed to increase 2.74 kg of glass from temperature 35 K to 77 K?

Question 7

The mass of calorimetry cup will be needed for measurements.

True

False

Fahrenheit

Celsius

Kelvin

Explanation / Answer

1) percentage difference is 41.41

x%=156/1.27=122.83

x%= 127/1.56=81.410

2)the specific heat of water is 4.179 J/g0C

3) The heat capacity defines the heat stored in an object at a certain time.    False

4)

Object A and C are in thermal equilibrium; Object B and C are in thermal equilibrium as well. Then object A and B must also be in thermal equilibrium.

True    zeroth law of thermodynamics

5) SI unit for temperature is kelvin

6) heat in kJ is needed to increase 2.74 kg of glass from temperature 35 K to 77 K is 9666.74*10^3 J Q= mc(dT)      c of glass is 84 J/g0C

7)The mass of calorimetry cup will be needed for measurements.    True
