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? °c apart 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. Let $T_{in}=40^{\circ}C$ and $T_{out}=15^{\circ}C$. The formula is $T = T_{in}-T_{out}$.
$T=40 - 15$

Step2: Solve the subtraction

$40-15 = 25$

Answer:

1. $25$
2. The change in surrounding temperature for a person going from inside to outside is also the difference between the inside and outside temperatures. So the answer is $25^{\circ}C$.
