Pre-Test Specific Heat of Solid (K2)

The working principle of the specific heat of solid experiment refers to the principle of…

• Black’s principle

• Hooke’s principle

• Archimedes’ principle

• Bernoulli’s principle

The following are the objectives of the specific heat of solid experiment, except…

• To understand the working principle of a calorimeter

• To determine the specific heat of a solid

• To predict the temperature decrease of the solid

• To predict the temperature increase of the solid

Specific heat can be defined as…

• The ratio between the heat capacity of a substance and the heat capacity of another substance in a different phase

• The specific heat capacity of a substance compared to the average kinetic energy of its molecules

• The ratio between the total energy of a substance and the specific heat capacity of water at a certain temperature

• The specific heat of a substance is the ratio between the heat capacity of the substance and the heat capacity of water

What is the statement of the principle based on the previous question's answer?

• The force required to stretch or compress a spring is proportional to the change in its length, provided the elastic limit is not exceeded

• In the flow of an incompressible fluid and in steady flow, the sum of pressure, kinetic energy, and potential energy per unit mass remains constant along the streamline

• Parts of a substance in an isolated system will exchange heat, where the heat released by the substance at a higher temperature is equal to the heat absorbed by the substance at a lower temperature

• An object partially or completely immersed in a fluid will experience an upward force equal to the weight of the fluid displaced by the object

The following are steps of the experiment:

1) Weigh and record the mass of the metal.

2) Measure the initial temperature of the water in the calorimeter.

3) Place the calorimeter in a jacket.

4) Measure the temperature of the metal and transfer it to the calorimeter.

5) Boil water.

6) Cool the calorimeter.

Define the appropriate specific heat formula if it is known that Q_released = Q_received…

• (m_b . c_b . ΔT_b) . (m_a . c_a . ΔT_a) = (m_c . c_c . ΔT_c)

• (m_b . c_b . ΔT_b) /(m_c . c_c . ΔT_c) = (m_a . c_a . ΔT_a)

• (m_b . c_b . ΔT_b) = (m_a . c_a . ΔT_a) + (m_c . c_c . ΔT_c)

• (m_b . c_b . ΔT_b) = (m_a . c_a . ΔT_a) - (m_c . c_c . ΔT_c)
