In which container did the liquid gain more energy?
c. In which container did the liquid gain more energy or did both gain the same amount? Explain your reasoning. Both liquids gained the same amount of energy because the heating rate was the same.

When a substance is heated the temperature of that substance increases will the same amount of energy?
energy will be transferred from the warmer object to the cooler one. The movement of thermal energy from a substance at a higher temperature to one at a lower temperature is called heat. When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.
What is the Calorimetry equation?
The equation for calorimetry is Q = mc∆T, where Q= heat evolved, m= mass, c= specific heat capacity and ∆T= change in temperature. 3.
What is calorimetry used for?
Calorimetry is used to measure amounts of heat transferred to or from a substance. To do so, the heat is exchanged with a calibrated object (calorimeter). The temperature change measured by the calorimeter is used to derive the amount of heat transferred by the process under study.
How do you find the mass of water in a calorimeter?
The volume of water is given but not the mass. Hence volume is converted into mass by using the density of water, which 1.0 g /ml. Therefore, Mass of water = 250 ml x 1.0 g/ml = 250 g Then the heat is evaluated using the following equation.
What is the difference between thermal energy and kinetic energy?
Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
How do you calculate thermal energy from kinetic and potential energy?

Does mass increase with heat?
The mass remains the same. The volume increases. And thus the density decreases. So, for example, a bar might appear longer when heated, but it will weigh the same.
Why is water good for a calorimeter?
Water has a high specific heat, which means it is difficult to increase the temperature of water. However, water also has the capacity to retain heat, which allows the other substance inside the calorimeter to absorb that heat.
Which law is used in calorimeter?
the law of conservation energyThe principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body.
What is the heat capacity of water?
4,184 JoulesOne of water's most significant properties is that it takes a lot of energy to heat it. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C.
How do you solve heat energy?
To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature.

How do you solve for heat capacity?
To calculate heat capacity, use the formula: heat capacity = E / T, where E is the amount of heat energy supplied and T is the change in temperature. For example, if it takes 2,000 Joules of energy to heat up a block 5 degrees Celsius, the formula would look like: heat capacity = 2,000 Joules / 5 C.
How many kJ are required to heat 45.0 g of h20 at 25.0 c and then boil it all away?
1 Answer. The answer is 116 kJ .
