Why would the calculated value of the specific heat be larger than the expected value?

The value of the specific heat capacity of water ,c determined in the experiment is larger than the standard value of c. This is because the experimental value of the temperature rise ,q less than the expected temperature rise due to some heat loss to the surroundings.

What does a smaller value of specific heat mean?

Explanation: Specific heat is Jg−oK . So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it.

Will the experimental values for specific heat be higher or lower than the actual values?

And when you plug your calculated temperature change into the specific heat capacity equation, your calculated experimental specific heat capacity would be smaller than the actual specific heat capacity.

What would cause the water to heat more than you expected?

The capability for a molecule to absorb heat energy is called heat capacity, which can be calculated by the equation shown in the figure. Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely.

Will this unmeasured heat loss increase or decrease the calculated value of the specific heat of the metal explain?

The unmeasured heat loss will cause the calculated value of the specific heat to decrease. This is because the energy lost by the metal is {eq}-q_m =…

What would be some errors when measuring the specific heat of a metal?

One of the common sources of error in the determination of the specific heat capacity of a metal is that some heat is lost during the transfer of a metal from the boiling water to the calorimeter.

Which has lowest specific heat capacity?

Mercury has a low specific heat capacity . Therefore it does not take much heat from the body whose temperature is to be measured. Otherwise it will lower the temperature of the body.

Does higher specific heat capacity mean?

The higher the specific heat capacity, the smaller the temperature change for the same amount of heat applied to the same mass of substance.

What determines specific heat capacity?

This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.

How does heat capacity differ from specific heat capacity?

Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.

Why does water have a much higher specific heat capacity than most liquids?

Originally Answered: Why does water have a high specific heat capacity compared to many other substances? This is because water unlike most liquids form hydrogen bonds, the strongest intermolecular force, different than intramolecular bonds that are way stronger.

Why was the specific heat lower than the accepted value?

The specific heat was lower than the accepted value for both trials because the DT of water and the DT of aluminum were not sufficient. Although the procedure asked for a specific amount of water in the 250 mL beaker, it did not ask for a specific amount of aluminum balls in the test tube or distilled water in the foam cup.

What is the specific heat capacity of water?

The average value of the specific heat capacity of water is , the table value is 4180 J·kg −1 ·K −1; the measurement error is about 5 \% of this value.

How do you calculate the specific heat of a substance?

The principle of your experiment is called calorimetry. Where you heat up the object (who’s specific heat you want to calculate) and then drop it into some liquid (usually water). By figuring out how much the temperature in water rises, we can figure out the specific heat.

How does specific heat affect the speed of heat change?

If a substance changes temperature quickly, it has a low specific heat capacity, meaning that a comparatively smaller amount of energy is required to change the temperature. If the specific heat capacity was higher, it would take more energy, which would result in a longer time taken to heat the object.
