How do you improve the efficiency of a calorimeter?
This can be reduced by insulating the sides of the calorimeter and adding a lid….They include:
- the volume of water used.
- the starting temperature of the water.
- the temperature increase.
- the distance of the flame from the calorimeter.
What makes a good calorimeter?
The calorimeter is a small container made of a metal, such as gold or copper, with good thermal conductivity. It has a well for a temperature sensor, which always has to be at exactly the same temperature as the calorimeter and its contents.
Would a calorimetry experiment work with ethanol instead of water?
Yes we can use ethanol too in calorimetry.
How does a calorimeter reduce heat loss?
Heat loss due to conduction is prevented by placing the calorimeter box in a well-lagged vessel using wool or cork material. Heat loss due to convection is prevented by placing a lid on the box. Heat loss due to radiation is minimized by polishing the box in order to smoothen it.
Which metal is used for calorimeter?
copper
Calorimeters are made of thin sheet of copper. For a calorimeter to be effective it must have two properties. (1) Although any object will use or loose some heat in experiments, a calorimeter should not absorb / loose too much of heat, otherwise it would affect the readings and final results.
Which is the best liquid to use in a calorimeter?
It is derived from the Latin word “calore” meaning “heat.” Water is best to use in a calorimeter because it has a high specific heat, however, other liquids such as ethanol can also be used.
How is the mass of water used in calorimetry?
The temperature change of the water is measured in the experiment and the specific heat of water can be used to calculate the heat absorbed by the surroundings . In the equation, is the mass of the water, is the specific heat of the water, and is .
Where does the word calorimeter come from in science?
A calorimeter is a scientific device used to measure changes in heat during chemical reactions and the heat capacity of different substances. It is derived from the Latin word “calore” meaning “heat.”
Can a thermometer still measure the temperature of water?
As a result of its high specific heat, water can absorb a great deal of heat while remaining in the liquid phase. This means that you can still measure the temperature using a standard thermometer.
