If the temperature of a body is increased by 5°C, then on Fahrenheit scale its temperature will increase by:

CONCEPT:

Celsius scale:

• In this scale, a lower fixed point (ice point) is taken 0° and the upper fixed point (steam point) is taken 100°.
• On the Celsius scale, there are 100 equal intervals between two reference points.

Fahrenheit scale:

• This scale of temperature has a lower fixed point at 32° F and an upper fixed point at 212° F.
• On the Fahrenheit scale, there are 180 equal intervals between two reference points.

The relation between the Fahrenheit temperature (t_F) and the Celsius temperature (t_C) is given as,

CALCULATION:

Given Δt_C = 5°C

We know that the relation between the Fahrenheit temperature (tF) and the Celsius temperature (tC) is given as,

Let the temperature at first is C₁ degree Celsius, and then it increased by 5° to C₂ degree Celsius, hence the difference between the initial and final temperature is given by

C₁ - C₂ = 5

Let the temperature is F₁ degree Fahrenheit corresponding to C₁ degree Celsius and F₂ degree Fahrenheit

When the temperature in degrees Celsius changed to C₂ which can be calculated from the formula.

, 

Then the difference in temperature in degrees Fahrenheit equal to

Where C₁ - C₂ = 5
