What will happen if a substance has a high specific heat capacity?
The higher the specific heat capacity, the smaller the temperature change for the same amount of heat applied to the same mass of substance.
When a metal with a higher specific heat is used How does that effect the final water temperature?
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.
What does specific heat capacity affect?
Unlike the total heat capacity, the specific heat capacity is independent of mass or volume. It describes how much heat must be added to a unit of mass of a given substance to raise its temperature by one degree Celsius.
What does it mean to have high specific heat capacity?
A high specific heat capacity means it can hold a large amount of thermal energy in for a low mass or temperature change.
Why metals have low specific heat capacity?
Metal atoms in pure metal are very close together and are able to transfer heat easily via conduction from one atom exciting the other atoms next to it. So the amount of energy it takes to heat a metal is relatively small to that of water for example.
What is the difference between total heat capacity and specific heat?
The difference between specific heat and heat capacity is the difference of mass in the calculation. Both of them are defined as the amount of energy required to raise the temperature but, in specific heat, the capacity is calculated per unit mass of a substance.
Do metals have high or low specific heat capacities?
Specific heat is a property that is specific to a given type of matter, and substances vary in their specific heat. Metals tend to have low specific heat. Water has very high specific heat.
What is heat capacity of metal?

How do different metals affect the temperature of water?
Each different type of metal causes the temperature of the water to increase to a different final temperature. This indicates that each metal has a different ability to absorb heat energy and to transfer heat energy. The ability of a substance to contain or absorb heat energy is called its heat capacity.
What is the best way to study specific heat capacity of metals?
Use experimental data to develop a conceptual understanding of specific heat capacities of metals. 2. Given appropriate calorimetry data for two metals, predict which metal will increase the temperature of water the most. 3. Use experimental data to develop a relationship among the variables: heat, mass, specific heat, and change in temperature.
Does specific heat increase the temperature of a body?
For the same amount of heat a body with a higher specific heat will have lesser temperature rise than a body with lower specific heat. No, heat capacity is the amount of energy a material can store per unit mass. It means the higher the heat capacity the more energy it need to raise the temperature by one degree.
Do the electrons in a metal contribute to its heat capacity?
In reality, the electrons in a metal do contribute to the heat capacity, but much much less than this. So much less that at room temperature, the heat capacity is really dominated by the vibration of the atoms, and you can ignore the electrons. This is another quantum effect.
