Chapter 18, Problem 1CQ

To determine

Position of the given temperatures T₁, T₂ and T₃ from highest to lowest.

Answer to Problem 1CQ

Solution:

T₂ > T₃>T₁

Explanation of Solution

The method used is:

1. Convert all the temperatures with a common unit.
2. Then, arrange them into descending order.

Given:

• T₁= 0 K
• T₂ = 0 °C
• T₃ = 0 °F

Calculation:

T₁ = 0 K

° F = 9/5 (K - 273) + 32

So, T₁ = 0K = -459.4 ° F

T₂ = 0 ° C

° F = 9/5 (° C) + 32

T₂ = 32 ° F

T₃ = 0 ° F

Arranging from higher to lowest we get:

T₂ > T₃>T₁

Conclusion:

Thus, order of temperatures from highest to lowest is T₂ > T₃>T₁
