Question

Air becomes liquid at 82 K and solid at 61 K .Convert these temperature on Celsius scale

Answer 1

82 K = 273+82 = 355 degree celcius

61 K = 273+61 = 334 degree celcius

Answer 2

Given:

Condensation temperature = 82K

The temperature at which air becomes solid = 61K

To Find: Temperature on the celsius scale

Solution:

• "K" depicts Kelvin.

• These are phase change temperatures.
• The process of conversion of gas to solid is called Condensation.
• When the liquid is cooled to an even lower temperature, Liquid changes to solid.

Formula used:

K - 273.15 = C

0°C = 273.15K

Applying the above Formula:

82K

82 - 273.15 = -191.15C

61K

61 - 273.15 = -212.15C

Hence, 82 K and 61 K are -191.15C and -212.15C temperatures on the Celsius scale respectively.
