Question

The average temperatures on the surface of five planets are given. Arrange the planets in decreasing order of their temperatures.
Earth 15 degrees Celsius

Saturn -139 degrees Celsius

Venus 468 degrees Celsius

Neptune -201 degrees Celsius

Mars -29 degrees Celsius

Answer 1

Hello!

The answer is:

1. Venus, with 468° C (degrees Celsius).
2. Earth, with 15° C (degrees Celsius).
3. Mars, with -29° C (degrees Celsius).
4. Saturn, with -139° C (degrees Celsius).
5. Neptune, with -201°C (degrees Celsius).

Why?

Decreasing order of their temperatures means ordering from the higher to the lower temperatures, so:

1. Venus, with 468° C (degrees Celsius).
2. Earth, with 15° C (degrees Celsius).
3. Mars, with -29° C (degrees Celsius).
4. Saturn, with -139° C (degrees Celsius).
5. Neptune, with -201°C (degrees Celsius).

Remember, when we are talking about sub-zero temperatures, the rule of what number is bigger than other, is inverted, for example, -201° C is lower than -139° C, meaning that the "bigger" the number, the lower the temperature. On the opposite side, if we are talking about not sub-zero temperatures (over 0°C) the "bigger" the number, the higher the temperature.

Have a nice day!
