To calculate the heat capacity of a calorimeter containing water, you can use the formula Q mcT, where Q is the heat absorbed or released, m is the mass of water, c is the specific heat capacity of water, and T is the change in temperature. By measuring the temperature change when a known amount of heat is added or removed from the water in the calorimeter, you can determine the heat capacity of the calorimeter.

A metal object with mass of 19g is heated to 96 Celsius then transferred to calorimeter containing 75 grams of water at 18 Celsius It reaches a temperature of 22 Celsius What is the specific heat?
The specific heat capacity of the metal object can be calculated using the formula q = mcΔT, where q is the heat transferred, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. The heat gained by the metal is equal to the heat lost by the water in the calorimeter, so q_metal = -q_water. By setting up the equation and solving for c, you can find the specific heat capacity of the metal.

In calculating the heat given off by a reaction in a calorimeter you must account for heat absorbed by?
In calculating the heat given off by a reaction in a calorimeter, you must account for heat absorbed by the surroundings, including the calorimeter itself, any water or solution in the calorimeter, and the air around the calorimeter that may be affected by the reaction. This ensures an accurate measurement of the heat released or absorbed by the reaction itself.
What is water equivalent of calorimeter?
The water equivalent of a calorimeter is the mass of water that would absorb or release the same amount of heat as the calorimeter itself for a given temperature change. It is a way to express the heat capacity of the calorimeter in terms of water, facilitating easier calculations in calorimetry experiments. The water equivalent is calculated by considering the specific heat capacity of the calorimeter's materials and their mass. This concept helps in determining the overall heat transfer during thermal processes.

To calculate the energy released within a calorimeter the volume temperature change and specific heat capacity of water must be known is this true or false?
True. To calculate the energy released within a calorimeter, you need to know the volume of the substance, the temperature change, and the specific heat capacity of the substance (in this case, water). This information is necessary to apply the formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change.
A 0.48g sample of graphite is placed in a bomb calorimeter with an excess of oxygen The water and calorimeter are at 25 c The graphite is ignited and burned and the water temperature rises to 28.05c?
The heat released by burning the graphite can be calculated using the temperature rise of the water and the heat capacity of the calorimeter. Firstly, calculate the heat absorbed by the water: Q = m * c * ΔT, where m is the mass of water and c is its specific heat capacity. Then, subtract the heat absorbed by the water from the total heat released by the graphite to find the heat produced by the combustion of the graphite.
What is the principle of Bunsen calorimeter?
The Bunsen calorimeter principle is based on the law of conservation of energy, where the heat released or absorbed in a chemical reaction is equal to the heat gained or lost by the surrounding water in the calorimeter. By measuring the temperature change of the water, one can calculate the heat exchanged in the reaction.
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.
What does a calorimeter use the increase in water temperature for?
A calorimeter uses the increase in water temperature to calculate the amount of heat transferred in a chemical reaction or physical process. By measuring the temperature change of the water, the calorimeter can determine the amount of heat absorbed or released by the reaction.

What error is introduced by including only the water in the calorimeter as the surroundings?
By considering only the water in the calorimeter as the surroundings, the error introduced is neglecting the heat exchange between the water and the actual surroundings outside the calorimeter. This can lead to an inaccurate measurement of the heat flow between the system being studied and the surroundings, affecting the calculated heat capacity or enthalpy change.

What type of calorimeter is junkers caloriemeter?
A Junkers Calorimeter is a device for determining the heating capacity of a gas - that is, how many joules one can get by burning a set volume of that gas. It's usually [natural] gas from the mains, but could be any flammable gas. The device is essentially a Bunsen burner with a cooling jacket. The jacket is cylindrical in shape, about 80cm tall, with water running through it. The burner sits inside the cylinder. The calorimeter allows the user to measure the temperature of water flowing in and flowing out. Once steady-state is reached, with those two temperatures steady, the water flowing through is collected for a specified period of time. Measuring the mass of the water and the temperature rise in the water, the operator can calculate the number of joules which went into the water to heat it. There is a flow meter on the fuel gas, so the operator can also calculate the volume of gas that was burned in the same time period. The amount of energy, in J, available per litre of gas can then be calculated. A Junkers calorimeter is a flow calorimeter, with heat transfer happening continuously, as opposed to a batch calorimeter. The design dates back to the late 1800s.
How do you use a calorimeter?
A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated. To use the calorimeter heat the liquid you want (or cool) and place it in the calorimeter cup and put that in the calorimeter and place the lid on top and the thermometer in the thermometer's hole. There you go. Simple as that. A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated.
