Question

Lab: Thermal energy transfer

Answer 1

Answer:Thermal energy transfer involves the transfer of internal energy.

Step-by-step explanation:

Three types of thermal energy transfer are conduction, convection and radiation.

Answer 2

The 100-gram samples will heat up faster than the 200-gram samples.

The mass of a substance plays a crucial role in determining its rate of heating. According to the formula

`\(Q = mc\Delta T\)`, where Q is the heat absorbed, m is the mass, c is the specific heat capacity and
`\(\Delta T\)` is the temperature change.

The mass directly influences the amount of heat needed for temperature alteration. Larger masses require more energy for heating due to their increased heat capacity.

Thus, 100-gram samples of the materials shown in the image will heat faster than the 200-gram samples irrespective of the initial temperatures.
