Question

a group of people are in a sweat lodge for a ceremony. the temperature inside the sweat lodge is 40°c. outside the sweat lodge, the temperature is 15°c. answer 2 questions about the sweat lodge. 1. how far apart were the temperatures inside and outside of the sweat lodge? 2. what was the change in surrounding temperature for a person who went from inside the sweat lodge to outside?

Explanation:

Step1: Calculate temperature difference

To find how far - apart the temperatures are, subtract the outside temperature from the inside temperature. The formula is $T_{difference}=T_{inside}-T_{outside}$.
$T_{inside} = 40^{\circ}C$ and $T_{outside}=15^{\circ}C$. So, $40 - 15=25$.

Step2: Determine temperature change

The change in surrounding temperature for a person going from inside to outside is the same as the temperature difference calculated above. The temperature decreases from $40^{\circ}C$ to $15^{\circ}C$, and the change is $40 - 15 = 25^{\circ}C$. The negative sign indicates a decrease. But when we talk about the magnitude of the change, it is $25^{\circ}C$.

Answer:

1. $25$
2. $25$
