Errors in measuring specific heat can be minimized by the following :
( 1 ) having a very well insulated calorimeter\
( 2 ) having a well calibrated calorimeter
( 3 ) having accurate measurements of the masses
( 4 ) having accurate measurements of the temperatures.

How do you determine the specific heat capacity of an object by method of cooling?
the spesific heat capacity of a liquid by the mithod of cooling
What appliances uses the property of air being a bad conductor of heat?
Double glazed windows contain a layer of air between two glass windows. As air is a poor conductor of heat so the heat loss through windows is minimized. Cavity wall employs polystyrene foam that traps a large amount of air in it. As air is a poor conductor of heat so the heat loss through the walls is minimized.
Specific heat of rice?
rice specific heat
Determine the amount of heat required to raise the temperature of 45.0 kg of quartz from 20oC to 35oC. The specific heat capacity of quartz is 0.739 J g K.?
10 641,6 kJ
Effect of temperature on specific heat of material?
The effect of temperature on specific heat of material is referred to as specific heat capacity.
What is the electrical method to determine the specific latent heat of vaporisation?
coclude the specific latent heat of vaporization
How do you determine the specific heat capacity of an object by method of cooling?
the spesific heat capacity of a liquid by the mithod of cooling
How do you determine heat specific heat capacities?
place two matterals each at different tempratures in contact with each other.
What constant is needed to determine the energy needed to warm the water to 25.C?
The answer is SPECIFIC HEAT!
What equipment is used in the lab to determine the specific heat of a substance?
Most common people say a thermometer
Why the experimental value of specific heat capacity is higher than the standars value?
Experimental errors would cause the experimental value of specific heat capacity to be higher than the standard value.
Correct units to determine specific heat?
Specific heat is the heat required to raise the temperature of a unit mass by one degree. It is measured by joules.
How do you determine specific heat for sodium without water?
Sodium reacts explosively with water, so it is not advisable to do a specific heat experiment with water. Instead use a non-exploding solution such as naphtha or a chlorobezene.
Why is a measured amount of water needed to determine the specific heat of a metal object?
Because the heat energy absorbed or released by the water is dependent on the mass of the water. q=m x c x delta T The equation tells you that you need a mass, a specific heat and a change in temperature to figure out the specific heat of the metal.
What factors determine the lengths of the flat regions of the graphs and the slope of the curves between the flat regions?
Specific heat capacity
What metal has the specific heat of 0.30?
There are three metals that have this specific heat cast iron, chromium and iron. You have to check the physical characteristics of the metal you used in your lab to determine which out of the three is the correct one.
