Question

Which of the following shows the maximum rise in temperature?

• A. $0°C$ to $10°C$
• B. $-4°C$ to $8°C$
• C. $-15°C$ to $-8°C$
• D. $-7°C$ to $0°C$

Answer 1

The correct option is B

$-4°C$ to $8°C$

Explanation for the correct option:

Correct option: Option B ( $-4°C$ to $8°C$)

To find the maximum rise in temperature, let us find the rise in temperature for all the four options.

The difference in temperature from $0°C$ to $10°C$ $=10°C-0°C$

$=10°C$

The difference in temperature from $-4°C$ to $8°C$ $=8°C-(-4°C)$

$=12°C$

The difference in temperature from $-15°C$ to $-8°C$ $=-8°C-(-15°C)$

$=7°C$

The difference in temperature from $-7°C$ to $0°C$ $=0°C-(-7°C)$

$=7°C$

The maximum temperature out of $10°C$, $12°C$, $7°C$ and $7°C$ is $12°C$.

So, the maximum rise in temperature is from $-4°C$ to $8°C$.

Hence, Option B is the correct option.

Explanation for the incorrect options:

Option A : $0°C$ to $10°C$

The difference in temperature from $0°C$ to $10°C$ is $10°C$.

$10°C$ is not the maximum temperature among $10°C$, $12°C$, $7°C$ and $7°C$.

Hence, Option A is the incorrect option.

Option C: $-15°C$ to $-8°C$

The difference in temperature from $-15°C$ to $-8°C$ is $7°C$.

$7°C$ is not the maximum temperature among $10°C$, $12°C$, $7°C$ and $7°C$.

Hence, Option C is the incorrect option.

Option D: $-7°C$ to $0°C$

The difference in temperature from $-7°C$ to $0°C$ is $7°C$.

$7°C$ is not the maximum temperature among $10°C$, $12°C$, $7°C$ and $7°C$.

Hence, Option D is the incorrect option.
