Lab No 1. HOT BALLOON
OBJECTIVE
To demonstrate water's enormous capacity to absorb heat withoutchanging temperature.
a) Inflate one balloon, and tie a knot at the top. After lighting a burner, put the balloon near the burner.
What you think will happen with the balloon?
a)Stay inflated
b) Burst
c) Stretch the balloon
b) Fill the other balloon with water and tie a knot at the top. After lighting a burner, put the balloon near the burner.
What youthink will happen with the balloon?
a) Stay inflated
b) Burst
c) Stretch the balloon
PRODUCT
a) Heat capacity and Specific heat. Explain the concepts and indicatethe corresponding units.
Heat capacity: the ratio of heat supplied to the corresponding rise in temperature of the body.
Specific Heat: the quantity of heat required to raise thetemperature of a unit mass through one degree.
b) Explain the results obtained in parts A and B.
In part A the balloon burst because the air has a low capacity of heat, the air hasno specific heat because it has no mass with it.
In part B the balloon expanded because instead of heating the latex of the balloon the water absorbed the heat. Water has a highcapacity of heat therefore the balloon didn’t burst. The specific heat of water is 1cal/gCº.
CONCLUSION
With this experiment we differ heat capacity and specific heat. Heat capacity isthe property of an object while specific heat capacity is the property of matter.
