# Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Q1.What is the independent variable?

1/5

Q2.How long would it take a 20 W motor to transfer 100 J of energy?

2/5

Q3.Why is no insulation placed beneath the beaker in the experiments to investigate insulation?

3/5

Q4.Put these steps in the right order for this method.
Insert the thermometer through the hole in the lid so that its bulb is in the hot water.
Add a lid to the beaker.
Put 80 cm³ of hot water into the beaker.
Record the temperature of the water every 3 minutes for 15 minutes.
