Question

to determine what size heater a building requires, engineers must calculate temperature lift. temperature lift is the temperature needed inside the building minus the lowest expected outside temperature. the inside of building needs to be heated to 20°c. the lowest outside temperature is -15°c. what is the temperature lift? a) 35°c b) 5°c c) -35°c d) -5°c

Explanation:

Step1: Identify the formula for temperature lift

Temperature lift = Inside temperature - Outside temperature.

Step2: Substitute the given values

Inside temperature is \(20^\circ\text{C}\), Outside temperature is \(-15^\circ\text{C}\). So, Temperature lift = \(20 - (-15)\).

Step3: Simplify the expression

Subtracting a negative is like adding the positive, so \(20 - (-15)=20 + 15 = 35\).

Answer:

A) \(35^\circ\text{C}\)
