Planet Average Temperature
Venus 460°C
Earth 14°C
Mars -60°C
Neptune -214°C
The net change in temperature from Neptune to Mars is °C.
The net change in temperature from Earth to Neptune is °C.
The net change in temperature from Venus to Earth is °C.

Answer 1

• Neptune to Mars: +154 °C
• Earth to Neptune: -228 °C
• Venus to Earth: -446 °C

Explanation:

Net change from the first to the second is found by subtracting the first from the second.

a) Mars - Neptune = (-60 °C) - (-214 °C) = (-60 +214) °C = 154 °C

b) Neptune - Earth = (-214 °C) - (14 °C) = -228 °C

c) Earth - Venus = (14 °C) - (460 °C) = -446 °C
