Use the equation: q=c*m*^T
Let q be heat absorbed or released. c is the specific heat. m is the mass. Let ^T be change in heat.
For example: Determine the specific heat of a material if a 12g sample absorbs 48J of heat as the temperature rises from 20`C to 40`C.
48J=c*12g*(40`C-20`C)
c= 0.20 J/g*`C

What is a substance that has a specific heat?
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
Which item the towel the sand or the water - has the highest specific-heat capacity?
Water has the highest specific heat capacity among the three items. This means it can absorb or release a lot of heat energy without undergoing a large change in temperature. Sand and towels have lower specific heat capacities compared to water.
Why does gold take less heat energy than water to change temperature?
Gold takes less heat energy than water to change temperature due to its lower specific heat capacity. Specific heat capacity is the amount of heat required to raise the temperature of a substance by one degree Celsius. Water has a high specific heat capacity, meaning it can absorb more heat without a significant temperature change, while gold, being a metal, has a much lower capacity, allowing it to heat up or cool down more quickly with less energy input.
How many joules would be required to heat 0.5kg of aluminum?
The specific heat capacity of aluminum is 0.897 J/g°C. To calculate the energy required to heat 0.5kg of aluminum by a certain temperature change, you would use the formula: Energy = mass x specific heat capacity x temperature change If you have the temperature change, you can plug the values into the formula to find the total energy in joules.
What is the dimensional formula of energy?
the formula to find specific heat is specific heat= calories/mass X change in temperature.
Does lower or higher specific heat hold more energy?
A substance with a higher specific heat can hold more energy because it can absorb or release more heat without changing its temperature significantly. This is because it requires more energy to raise the temperature of a substance with a higher specific heat compared to one with a lower specific heat.
How can you tell if something is a good insulator based on its specific heat?
Specific heat is a measure of how much heat energy a substance can absorb before its temperature changes. Typically, substances with higher specific heat are better insulators because they can absorb more heat energy without changing temperature quickly. Therefore, a substance with a higher specific heat is usually a good insulator.
How can one determine the amount of heat energy present in a system and what methods can be used to find heat energy?
One can determine the amount of heat energy in a system by measuring the temperature change and the specific heat capacity of the material. Methods to find heat energy include using calorimetry, thermometers, and equations such as Q mcT.
Why do you think water has a specific heat capacity?
Water has a high specific heat capacity because of its strong hydrogen bonding, which allows it to absorb and release heat energy without changing temperature quickly.
How can specific heat be determined without using the heat transfer value (q)?
Specific heat can be determined without using the heat transfer value by conducting an experiment where the initial and final temperatures of a substance are measured, along with the mass of the substance and the amount of heat added or removed. By using the formula Q mcT, where Q is the heat energy, m is the mass, c is the specific heat, and T is the change in temperature, the specific heat can be calculated.
Why is the correct equation rearranged to solve for specific heat?
The equation for specific heat, Q = mcΔT, can be rearranged to solve for specific heat by isolating c, the specific heat, which gives c = Q / (mΔT). This rearrangement allows us to find the specific heat capacity of a substance based on the amount of heat energy transferred, the mass of the substance, and the temperature change it undergoes.
What is the relationship between specific heat and latent heat in the context of thermal energy transfer?
Specific heat and latent heat are both properties of a substance that determine how it absorbs or releases thermal energy. Specific heat refers to the amount of heat required to raise the temperature of a substance by a certain amount, while latent heat is the amount of heat needed to change the state of a substance without a change in temperature. In thermal energy transfer, specific heat affects the temperature change of a substance, while latent heat is involved in phase changes such as melting or boiling.
Is there another term for specific heat?
Another specific term for heat is thermal energy for light it is radiant energy.
How To calculate Specific Heat of A compound Such as NaOH?
Specific heat is the measure of energy it takes to raise a unit mass in temperature by one degree Celsius. When measuring a compound that is water soluble, heat it separately to a specific range, then use the liquid to calculate the amount of heat that was used.
How do you heat water without energy?
No energy, no heat. So you cannot add heat.
What is the relationship between specific heat and heat transfer in a material?
The specific heat of a material determines how much heat energy is needed to change its temperature. Materials with higher specific heat require more heat energy to raise their temperature. This means that they can absorb more heat without a significant temperature change, making them good insulators. On the other hand, materials with lower specific heat heat up quickly and cool down quickly, making them good conductors of heat.
