You use a thermometer, to measure the temperature. As a guide to know how much heat to apply, the temperature reading must be kept within a certain range, to be constant.

What is the specific heat capacity of ethanol and how does it affect its ability to absorb and release heat compared to other substances?

The specific heat capacity of ethanol is 2.44 J/gC. This means that ethanol can absorb and release heat more efficiently compared to other substances, as it requires less energy to change its temperature. This property makes ethanol a good candidate for use in applications where heat transfer is important.


What term is use to describe the amount of energy it takes for a certain amount of substances to be raised one degree in temperature is it specific heat specific gravity specific energy specific mass?

The term used to describe the amount of energy required to raise the temperature of a substance by one degree Celsius is specific heat.


How can one calculate the equilibrium constant with temperature?

To calculate the equilibrium constant with temperature, you can use the Van 't Hoff equation, which relates the equilibrium constant to temperature changes. The equation is: ln(K2/K1) -H/R (1/T2 - 1/T1), where K is the equilibrium constant, H is the enthalpy change, R is the gas constant, and T is the temperature in Kelvin. By rearranging the equation and plugging in the known values, you can calculate the equilibrium constant at a specific temperature.


Suppose that 28 g of each of the following substances is initially at 27.0circ C What is the final temperature of each substance upon absorbing 2.45 kJ of heat?

To find the final temperature of each substance, you need to calculate the specific heat capacity of each substance. Once you have the specific heat capacity, you can use the formula Q = mcΔT to find the final temperature. Substituting the given values into the formula will give you the final temperature of each substance.


Why is water an excellent material to use in a calorimeter?

Water is an excellent material to use in a calorimeter because it has a very high specific heat, making it very hard for water to raise its temperature even by 1 degree celsius, but as hard as it was to raise the temperature of the water, it is equally as hard to lower the temperature of the water-making it able to effectively retain heat and allowing the other material inside of the calorimeter to absorb that heat.

Explain how you might keep a gas at a constant temperature during a thermodynamic process?

To keep a gas at a constant temperature during a thermodynamic process, you would need to provide or remove heat in such a way that the temperature of the gas remains constant. This can be achieved by using a heat reservoir that can absorb or provide heat to the gas as needed. Additionally, you could use a thermostat to monitor the temperature and adjust the heat input accordingly.


How to find the final temperature when two substances are mixed together?

To find the final temperature when two substances are mixed together, you can use the formula: (Tf frac(m1 times C1 times T1) (m2 times C2 times T2)(m1 times C1) (m2 times C2)) Where: (Tf) is the final temperature (m1) and (m2) are the masses of the substances (C1) and (C2) are the specific heat capacities of the substances (T1) and (T2) are the initial temperatures of the substances Simply plug in the values for the masses, specific heat capacities, and initial temperatures of the substances to calculate the final temperature.


Why you we use log mean temperature difference formula?

The use of the LMTD arises straightforwardly from the analysis of a heat exchanger with constant flow rate and fluid thermal properties. It is a simple method to approximated the temperature diving force in a heat exchanger. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. The larger the LMTD, the more heat is transferred.

Is Calculate the Calorimeter Constant if 25 g of water at 56C was added to 25 g of water at 25C with a resulting temperature of 35C?

To calculate the calorimeter constant, you first need to use the formula for heat transfer: q=mcΔT, where q is the heat transfer, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Since the two water samples reached thermal equilibrium, the heat lost by the hot water is equal to the heat gained by the cold water. By rearranging the equation to find the calorimeter constant, you can solve for it using the given data.

Can you use a charcoal starter to heat water tank?

A charcoal starter cannot readily be used to heat hot water tank as it produces far too little heat. A hot water tank requires several thousand BTU's of constant heat to bring the water up to temperature.


Is the silicone spatula heat resistant for use in high-temperature cooking?

Yes, the silicone spatula is heat resistant and safe to use in high-temperature cooking.


What does electrical appliances use to keep temperature constant?

Electrical appliances such as refrigerators and air conditioners use a thermostat to monitor the temperature and adjust the operation of the appliance to maintain a constant temperature. When the temperature rises or falls outside the set range, the thermostat signals the appliance to turn on or off to keep the temperature stable.


Does free energy lost as heat ever serve a useful function?

Yes, free energy lost as heat can serve a useful function by helping to regulate body temperature in warm-blooded animals. This heat loss is necessary to maintain a constant internal temperature in the face of changing external conditions. In addition, heat can also be harnessed for energy conversion processes in thermal power plants.


Why should you put the fin across gas side in heat exchanger application?

in my opinion because the gas is more efficient for trans heat to the material and we use the fins for icrease the heat transfer from the body to the surrounding and the gas will help for econtinuatioin heat transfer from the body because the gas not constant in its temperature and other properties
