Question

If temperature of warm water is 40°C Celsius and that of warm milk is 95°F Fahrenheit, which one of the following sentences is true?

• A. Milk has little greater temperature than water and warm.
• B. Both have same temperature.
• C. Milk has lesser temperature than water.
• D. Milk has higher temperature than water and hot.

Hint:

Always convert Fahrenheit to Celsius when comparing temperatures in different units. Remember that Celsius and Fahrenheit have different scales of measurement.

Answer 1

The Correct Option is D

To compare the two temperatures, we must convert them to the same unit. Let's convert the water's temperature from Celsius to Fahrenheit.
The formula for converting Celsius (C) to Fahrenheit (F) is: $F = \left(C \times \frac{9}{5}\right) + 32$.
Given the water's temperature is $C = 40^\circ$.
Substitute this value into the formula:
$F = \left(40 \times \frac{9}{5}\right) + 32$.
$F = (8 \times 9) + 32$.
$F = 72 + 32$.
$F = 104^\circ$F.
So, the temperature of the water is 104°F.
The temperature of the milk is given as 95°F.
Now we compare the temperatures:
Water temperature = 104°F.
Milk temperature = 95°F.
Since $95^\circ F<104^\circ F$, the milk has a lesser temperature than the water.
