Question

When the temperature of a water bath increases by 20 degree Celsius, The Mercury in the thermometer shoots 1 cm. If the temperature would be for the increase by 10 degree Celsius , by how much would the Mercury rise?

Answer 1

Answer:

0.5 cm

Explanation:

Using unitary method:

For 20℃; 1cm

For 10℃; 10/20

=0.5

Answer 2

The answer is 0.5 cm

GIVEN

When the temperature of a water bath increases by 20 degree Celsius, The Mercury in the thermometer shoots 1 cm. The temperature would be for the increase by 10 degree Celsius.

TO FIND

The rise in the mercury.

SOLUTION

We can simply solve the above problem as follows;

We are given,

Increase in temperature of the water bath = 20°C

Rise in the mercury = 1 cm

Applying basic unitary method;

Rise in the mercury with 1°C increase in the temperature = 1/20 cm

Rise in the mercury with 10°C rise in temperature = (1/20) × 10

= 0.5 cm

Hence, The answer is 0.5 cm
