What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What is the specific heat capacity of a wire?
The specific heat capacity of a wire depends on the material it is made of. For most metals, the specific heat capacity is around 0.5 - 0.9 J/g°C. It is a measure of how much heat energy is required to raise the temperature of one gram of the material by one degree Celsius.
How do you measure molar heat capacity?
Specific heat is the heat capacity divided by the heat capacity of water, which makes it dimensionless. To obtain molar heat capacity from specific heat for a material of interest, simply multiply the specific heat by the heat capacity of water per gram [1 cal/(g*C)]and multiply by the molecular weight of the substance of interest. For example, to obtain the molar heat capacity of iron Specific heat of iron = 0.15 (note there are no units) Molar heat capacity of iron = 0.15*1 cal/(g*C)*55.85 g /gmole = 8.378 cal/(gmole*C)
What is the speciic heat capacity of KNO3?
What is the specific heat capacity of kno3
Is the heat capacity of a body the same as its specific heat capacity?
The heat capacity depends on the mass of a material and is expressed in j/K.The specific heat capacity not depends on the mass of a material and is expressed in j/mol.K.
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What does heat capacity depend on?
Heat capacity depends on the substance's mass, the substance's specific heat capacity, and the temperature at which the substance is being heated. It is a measure of how much energy is required to raise the temperature of a substance by one degree Celsius.
What is the specific heat capacity by mechanical method?
The specific heat capacity by mechanical method involves measuring the amount of work done on a substance to change its temperature. This method typically uses a device like a bomb calorimeter to measure the heat capacity, which is then used to calculate the specific heat capacity of the substance. The specific heat capacity by mechanical method provides an accurate measurement of how much energy is required to raise the temperature of a substance by a certain amount.

The specific heat capacity of a wire depends on the material it is made of. For most metals, the specific heat capacity is around 0.5 - 0.9 J/g°C. It is a measure of how much heat energy is required to raise the temperature of one gram of the material by one degree Celsius.
To determine the specific heat capacity of a solid conclusion?
To determine the specific heat capacity of a solid, conduct an experiment where you measure the temperature change of a known mass of the solid when a known amount of heat is added or removed. By calculating the specific heat capacity using the formula Q = mcΔT (where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change), you can determine the specific heat capacity of the solid. Repeat the experiment multiple times to ensure accuracy and reliability in your conclusion.
When does the thermal capacity of a substance become equal to its specific gravity?
The thermal capacity of a substance, also known as specific heat capacity, and its specific gravity are two distinct properties and are not directly correlated. The specific heat capacity is a measure of the amount of heat energy required to raise the temperature of a substance by a certain amount, while specific gravity is a measure of a substance's density compared to the density of water. The two properties do not become equal to each other under normal conditions.
How do you measure molar heat capacity?
Specific heat is the heat capacity divided by the heat capacity of water, which makes it dimensionless. To obtain molar heat capacity from specific heat for a material of interest, simply multiply the specific heat by the heat capacity of water per gram [1 cal/(g*C)]and multiply by the molecular weight of the substance of interest. For example, to obtain the molar heat capacity of iron Specific heat of iron = 0.15 (note there are no units) Molar heat capacity of iron = 0.15*1 cal/(g*C)*55.85 g /gmole = 8.378 cal/(gmole*C)
The specific heat capacity of a liquid by an electrical heating method?
To determine the specific heat capacity of a liquid using an electrical heating method, you can measure the change in temperature of the liquid when a known amount of electrical energy is supplied. By using the formula Q = mcΔT (where Q is the heat energy supplied, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the temperature change), you can calculate the specific heat capacity of the liquid.
What is the specific heat capacity of Polyester?
The specific heat capacity of polyester is 2.35degrees
Which metal has the highest specific heat capacity?
No. Metals have a relatively low specific heat.
What is the speciic heat capacity of KNO3?
What is the specific heat capacity of kno3
Joules divided by Celsius times grams?
This calculation is used to find the specific heat capacity of a substance. The specific heat capacity is a measure of how much energy is needed to raise the temperature of a given amount of a substance by 1 degree Celsius. The formula used is: specific heat capacity = energy (in Joules) / (mass (in grams) * change in temperature (in Celsius)).
