Question

determine the change in temperature if a substance is heated from 25°c to 47°c.
a -22°c
b 72°c
c 22°c
d -72°c

Explanation:

Step1: Subtract the initial temperature from the final temperature

$$\Delta T=T_{final}-T_{initial}$$

Step2: Substitute the values

$$\Delta T = 47 - 25$$

Step3: Calculate the result

$$\Delta T=22$$

Answer:

C. \(22^{\circ}C\)
