Question

The Tempe of the melting point of ice and that of boiling point of water at normal atmospheric pressure are marked 40 and 200 respectively on a certain thermometer.what is 1the temperature in degree Celsius when the reading on this temperature is 80 2 the thermometer reading when the temperature is 60 degree Celsius

Answer 1

Answer:

Answer 2

1. The temperature in degrees Celsius when the reading on this temperature is 80 is 25°C

2. The thermometer reads 136° when the temperature is 60°C.

Given:

The melting point on the thermometer = 40

The boiling point on the thermometer is 200

To find:

The temperature in degrees Celsius when the reading on this temperature is 80

The thermometer reads when the temperature is 60 degrees Celsius.

Solution:

The number of equal parts on the given thermometer is 200 - 40 = 160

1. The temperature in degrees Celsius when the reading on this temperature is 80 is

$\frac{80 - 40}{160}$ = $\frac{t - 0}{100}$

or t = 25°C

2. The thermometer reads when the temperature is 60 degrees Celsius.

$\frac{t-40}{160}$ = $\frac{60 - 0}{100}$

or t - 40 = 96

or t = 136°

1. The temperature in degrees Celsius when the reading on this temperature is 80 is 25°C

2. The thermometer reads 136° when the temperature is 60°C.
