Objective
In this activity, you should be able to describe the condition
necessary for heat transfer to take place and trace the direction in which heat
is transferred.
Materials Needed
2 small containers (drinking cups or glasses)
2 big containers (enough to accommodate the small containers)
tap water
hot water
food coloring
laboratory thermometers (with reading up to 100
o
C)
Procedure
1. Label the small and big containers
as shown in Figure 2.
2. Half fill containers 1, 2, and A with
tap water. Half fill also container B
with hot water. Be careful when you
pour hot water into the container.
3. Add few drops of food coloring on
the larger containers.
4. Measure the initial temperature of
water in each of the 4 containers, in
degree Celsius (°C). Record your
measurements in Table 1.
5. Carefully place container 1 inside
container A (Figure 3). This will be
your Setup 1.
6. Place also container 2 inside
container B. This will be your Setup 2.
7. Measure the temperature of water in all containers 2 minutes after
arranging the setups. Record again your measurements in the table (after 2
minutes).
8. Continue to measure and record the temperature of water after 4, 6, 8, and
10 minutes. Write all your measurements in the table below.
