Question

The fact that desert sand is very hot in the day and very cold at night is evidence that sand has

A) a low specific heat.
B) a high specific heat.
C) no specific heat

Answer 1

The fact that desert sand is very hot in the day and very cold at night is evidence that sand has

A) a low specific heat. Answer: A

Explanation: Because the fact that desert sand is very hot in the day and very cold at night is evidence that sand has

A) a low specific heat.

Answer 2

A) a low specific heat.

Step-by-step explanation:

As we know that heat given to the sand will increase it temperature

so we can say

`Q = ms\Delta T`

here we will have

`\Delta T = (Q)/(ms)`

so now we will have

more change in temperature due to heat given to the sand will show that it must have low specific heat capacity as it inversely depends on the specific heat capacity of the sand

so correct answer will be

A) a low specific heat.
