the temperature was -3c last night .it is now -4c. what was the change in temperature.

Question

I just need a little help please

Answer 1

Just subtract the initial temperature from the final temperature.

 

ΔT = T₂ - T₁ = -4°C - (-3°C) = (-4 + 3)°C = -1°C

 

 

Answer 2

Hello Ruben

 

Let x = the change in temperature.

 

-3 + x = -4

 

x = -4 + 3 = -1 ºC
