Question
Which of the curves in the following figure represents the relation between Celsius and Fahrenheit temperatures?
Options
a
b
c
d
Solution
The correct option is (a).
Celsius and Fahrenheit temperatures are related in the following way:
C = `5/9"F" - 160/9`
Here, F = temperature in Fahrenheit
C = temperature in Celsius
If this equation is plotted on the graph, then the curve will be represented by curve 'a' lying in the fourth quadrant with slope 5/9.

An earthen pitcher loses 1 gm of water per minute due to evaporation. If the water equivalent of the pitcher is 0.5 kg and the pitcher contains 9.5 kg of water, calculate the time required for the water in a pitcher to cool to 28°C from the original temperature of 30°C. Neglect radiation effects. The latent heat of vaporization in this range of temperature is 580 Cal/gm and the specific heat of water is 1 Cal/gm°C.
