Question

Alfred left a thermometer outside on a warm, sunny day. It recorded the temperature of the surroundings at different times of the day as shown. The temperature of the surrounding is as follows:

• A. Increases throughout the day
• B. Decreases throughout the day
• C. at $4:00$ pm, is 36.8 ${}^{\circ }$C
• D. at $12:00$ pm, is 36 ${}^{\circ }$C

Answer 1

Answer: (A), (C)

at $4:00$ pm, is 36.8 ${}^{\circ }$C

• The rise in the level of mercury suggests the temperature of the surroundings increases throughout the day.
• At $12:00$ pm, the temperature is 35.6 ${}^{\circ }\text{C}$, i.e., $35+3$ division = $35+3\left(0.2\right)$ = 35.6 ${}^{\circ }\text{C}$.
• At $4:00$ pm, it has risen to 36.8 ${}^{\circ }\text{C}$
