Chapter 6, Problem 6.77E

Using the specific heat data of Table 6.8, calculate the amount of heat (in calories) needed to increase the temperature of the following:

a. 210 g of copper from 40. ° C to 95. ° C

b. 150 g of mercury from 120. ° C to 300. ° C

c. 2.50 × 10 3 g of helium gas from 250. ° C to 900. ° C

Interpretation Introduction

(a)

Interpretation:

To calculate the heat (in calories) required to increase the temperature of 210g copper from 40.°C to 95.°C.

Concept introduction:

When temperature is changed or the state of matter is changed the energy is either absorbed or released. The energy required to change temperature of matter is known as specific heat of matter. The energy required to change a state of matter is known as heat of fusion or vaporization.

Answer to Problem 6.77E

The amount of heat (in calories) required to increase the temperature of 210g copper from 40.°C to 95.°C is 1074.15cal.

Explanation of Solution

The formula to calculate amount of heat (in calories) required to increase the temperature is given below as,

Heat=(samplemass)(specificheat)(temperaturechange)

Substitute the values in the above equation as follows.

Heat=(samplemass)(specificheat)(temperaturechange)=(210g)(0.093calg°C)(95°C40°C)=(210g)(0.093calg°C)(55°C)=1074.15cal

Conclusion

The amount of heat (in calories) required to increase the temperature of 210g copper from 40.°C to 95.°C is 1074.15cal.

(b)

Interpretation:

The amount of heat (in calories) required to increase the temperature of 150g mercury from 120.°C to 300.°C is to be calculated.

Concept introduction:

When temperature is changed or the state of matter is changed the energy is either absorbed or released. The energy required to change temperature of matter is known as specific heat of matter. The energy required to change a state of matter is known as heat of fusion or vaporization.

Answer to Problem 6.77E

The amount of heat (in calories) required to increase the temperature of 150g mercury from 120.°C to 300.°C is 891cal.

Explanation of Solution

The formula to calculate amount of heat (in calories) required to increase the temperature is given below as,

Heat=(samplemass)(specificheat)(temperaturechange)

Substitute the values in the above equation as follows.

Heat=(samplemass)(specificheat)(temperaturechange)=(150g)(0.033calg°C)(300°C120°C)=(150g)(0.033calg°C)(180°C)=891cal

Conclusion

The amount of heat (in calories) required to increase the temperature of 150g mercury from 120.°C to 300.°C is 891cal.

(c)

Interpretation:

The amount of heat (in calories) required to increase the temperature of 2.50×103g helium gas from 250.°C to 900.°C is to be calculated.

Concept introduction:

When temperature is changed or the state of matter is changed the energy is either absorbed or released. The energy required to change temperature of matter is known as specific heat of matter. The energy required to change a state of matter is known as heat of fusion or vaporization.

Answer to Problem 6.77E

The amount of heat (in calories) required to increase the temperature of 2.50×103g helium gas from 250.°C to 900.°C is 2.03×106cal.

Explanation of Solution

The formula to calculate amount of heat (in calories) required to increase the temperature is given below as,

Heat=(samplemass)(specificheat)(temperaturechange)

Substitute the values in the above equation as follows.

Heat=(samplemass)(specificheat)(temperaturechange)=(2.50×103g)(1.25calg°C)(900°C250°C)=(2.50×103g)(1.25calg°C)(650°C)=2.03×106cal

Conclusion

The amount of heat (in calories) required to increase the temperature of 2.50×103g helium gas from 250.°C to 900.°C is 2.03×106cal.
