Question

A block of ice is cooled from -0.5 degrees Celsius to -10.1 degrees Celsius. Calculate the temperature change, delta T, in degrees Celsius and in kelvins.

Answer 1

Delta T= T final - T initial
Tfinal= -101.1 °C
Tinitial= -0.5 °C
•Delta T = -101.1°C - (-0.5°C)
=100.6°C

Kelvin= °C + 273
= -100.6 + 273
= 172.4 Kelvin
