(a)

To determine

The change in temperature from morning to afternoon in degree Celsius.

(a)

Expert Solution

Answer to Problem 5E

The change in temperature from morning to afternoon in degree Celsius is 12°C.

Explanation of Solution

Given info: The temperature in the morning is 18°C and in the afternoon is 30°C.

Write the expression for change in temperature

ΔT = T2−T1

Here,

ΔT is the change in temperature

T1 is the initial temperature

T2 is the final temperature

Substitute 18°C for T1 and 30°C for T2 in the above equation

ΔT = 30°C−18°C=12°C

Conclusion:

The change in temperature from morning to afternoon in degree Celsius is 12°C.

(b)

To determine

The initial temperature in the morning in Fahrenheit.

(b)

Expert Solution

Answer to Problem 5E

The initial temperature in the morning in Fahrenheit is 64.4 °F.

Explanation of Solution

Given info: The temperature in the morning is 18°C and in the afternoon is 30°C.

Write the expression for degree Celsius to Fahrenheit

T°F = 95T°C+32

Here,

T°F is the temperature in Fahrenheit

T°C is the temperature in degree Celsius

Substitute 18°C for T°C in the above equation

T°F = 95×18°C+32=64.4°F

Conclusion:

The initial temperature in the morning in Fahrenheit is 64.4 °F.

(c)

To determine

The final temperature in the afternoon in Fahrenheit.

(c)

Expert Solution

Answer to Problem 5E

The final temperature in the afternoon in Fahrenheit 86°F.

Explanation of Solution

Given info: The temperature in the morning is 18°C and in the afternoon is 30°C.

Write the expression for degree Celsius to Fahrenheit

T°F = 95T°C+32

Here,

T°F is the temperature in Fahrenheit

T°C is the temperature in degree Celsius

Substitute 30°C for T°C in the above equation

T°F = 95×30°C+32=86°F

Conclusion:

The final temperature in the afternoon in Fahrenheit 86°F.

(d)

Expert Solution

Answer to Problem 5E

The change in temperature from morning to afternoon in degree Fahrenheit is 21.6°F.

Explanation of Solution

Given info: The temperature in the morning is 18°C and in the afternoon is 30°C.

Write the expression for change in temperature

ΔT = T2−T1

Here,

ΔT is the change in temperature

T1 is the initial temperature

T2 is the final temperature

Substitute 18°C for T1 and 30°C for T2 in the above equation

ΔT = 30°C−18°C=12°C

Write the expression for degree Celsius to Fahrenheit

T°F = 95T°C+32

Here,

T°F is the temperature in Fahrenheit

T°C is the temperature in degree Celsius

Substitute 12°C for T°C in the above equation

T°F = 95×12°C=21.6°F

Conclusion:

The change in temperature from morning to afternoon in degree Fahrenheit is 21.6°F.

(e)

To determine

To explain why ΔT in Fahrenheit cannot calculate by converting ΔT in degree Celsius using usual conversion.

(e)

Expert Solution

Answer to Problem 5E

Both conversion in degree Celsius and Fahrenheit involves a term of +32. Taking the difference between the conversion equations of two temperatures from degree Celsius to Fahrenheit the part of 32 will cancels off. This makes the difference in the calculation.

Explanation of Solution

Given info: The temperature in the morning is 18°C and in the afternoon is 30°C.

Write the expression for degree Celsius to Fahrenheit

T°F = 95T°C+32

Here,

T°F is the temperature in Fahrenheit

T°C is the temperature in degree Celsius

Subtracting the above equations for 18°C and 30°C will results in the cancellation of the term 32 and the remaining equation contain only 95.

Conclusion:

Both conversion in degree Celsius and Fahrenheit involves a term of +32. Taking the difference between the conversion equations of two temperatures from degree Celsius to Fahrenheit the part of 32 will cancels off. This makes the difference in the calculation.

The change in temperature from morning to afternoon in degree Fahrenheit is 21.6°F.

Answer 34

(e)

To determine

To explain why ΔT in Fahrenheit cannot calculate by converting ΔT in degree Celsius using usual conversion.

(e)

Expert Solution

Answer to Problem 5E

Both conversion in degree Celsius and Fahrenheit involves a term of +32. Taking the difference between the conversion equations of two temperatures from degree Celsius to Fahrenheit the part of 32 will cancels off. This makes the difference in the calculation.

Explanation of Solution

Given info: The temperature in the morning is 18°C and in the afternoon is 30°C.

Write the expression for degree Celsius to Fahrenheit

T°F = 95T°C+32

Here,

T°F is the temperature in Fahrenheit

T°C is the temperature in degree Celsius

Subtracting the above equations for 18°C and 30°C will results in the cancellation of the term 32 and the remaining equation contain only 95.

Conclusion:

Both conversion in degree Celsius and Fahrenheit involves a term of +32. Taking the difference between the conversion equations of two temperatures from degree Celsius to Fahrenheit the part of 32 will cancels off. This makes the difference in the calculation.
