What is the specific heat capacity of kno3
Most specific heat capacities are found by combining a substance with another with a known specific heat usually water. But How do chemists know the specific heat capacity of water in the first place?
The specific heat capacity of water was initially determined through experiments involving measuring the temperature change when a known amount of water absorbs a certain amount of heat. The relationship between the heat absorbed, temperature change, and mass of water was used to calculate the specific heat capacity of water. This value has been confirmed and refined over time through numerous experiments and calculations.
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.
How do you determine specific heat capacity of a liquid?
To determine the specific heat capacity of a liquid, you can use a calorimeter. By measuring the initial and final temperatures of the liquid when it absorbs a known quantity of heat, you can calculate the specific heat capacity using the formula Q = mcΔT, where Q is the heat absorbed, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the change in temperature.
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.
What principle permits calorimetry to be used to determine the specific heat capacity of a substance?
The principle of energy conservation permits calorimetry to be used to determine the specific heat capacity of a substance. This principle states that energy cannot be created or destroyed, only transferred. Calorimetry utilizes this principle by measuring the heat exchanged between substances to determine specific heat capacity.
What is the process to calculate the specific heat of a calorimeter?
To calculate the specific heat of a calorimeter, you can use the formula q mcT, where q is the heat absorbed or released, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature. By measuring the heat absorbed or released and the other variables, you can solve for the specific heat capacity of the calorimeter.

What is the term for numbers and are obtained by counting or measuring?
The term for numbers obtained by counting is "discrete numbers," while those obtained through measuring are referred to as "continuous numbers." Discrete numbers can only take specific values, such as whole numbers, whereas continuous numbers can take any value within a range. Together, they represent different types of quantitative data used in various fields of study.
How do you calculate the heat capacity of a calorimeter?
To calculate the heat capacity of a calorimeter, you can use the formula Q mcT, where Q is the heat absorbed or released, m is the mass of the substance in the calorimeter, c is the specific heat capacity of the substance, and T is the change in temperature. By measuring the heat absorbed or released and the change in temperature, you can determine the heat capacity of the calorimeter.
What is the process to calculate the heat capacity of a calorimeter?
To calculate the heat capacity of a calorimeter, you can use the formula Q mcT, where Q is the heat absorbed or released, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature. By measuring the temperature change when a known amount of heat is added to the calorimeter, you can determine its heat capacity.
What is the specific heat problem and how does it impact the study of thermodynamics?
The specific heat problem refers to the challenge of accurately measuring and predicting the specific heat capacity of substances. This impacts the study of thermodynamics because specific heat capacity is a crucial parameter in understanding how substances store and release energy as heat. Inaccurate measurements can lead to errors in calculations and hinder the ability to predict and control thermal processes.
How to calculate calories in chemistry?
To calculate calories in chemistry, you can use the formula: Calories mass x specific heat capacity x temperature change. This formula helps determine the amount of energy required to raise the temperature of a substance. By measuring the mass of the substance, its specific heat capacity, and the temperature change, you can calculate the calories.
