Question
1. Which variable was the independent variable in this experiment? Heat Temperature Specific heat Energy Liquids 2. Which liquid had the highest specific heat capacity in your experiment? Water Alcohol Glycerine Hexane 3. What does a steeper line on the temperature against energy graph mean? Greater specific heat Lesser specific heat Can't tell without knowing mass Unrelated to specific heat 4. A new liquid is added to the experiment and measured to have a greater specific heat than water. How would the graph of temperature against energy look for this liquid? Steeper than for water Shallower than for water The same as water None of the above 5. Cold water has a substantially larger specific heat than warm water. True False Pouring honey 6. If you add equal amounts of heat to equal masses of water and alcohol, which will stay closest to its initial temperature? water alcohol both will be equal none of the above 7. Thicker liquids have higher specific heats. True False
Explanation / Answer
1. Heat and Specific heat is a independent variable. Cause specific heat is a intrinsic property of a material and does not depend on any thing. And if you heat someting its temperature and energy will rise. SO heat is independent.
2. It is water. Water has the highest specific heat among them.
3. Energy is specific heat multiplied by temperature. So for a given temperature the material which has higher specific heat will be steeper..
4. As like in 3, it should be steeper than water.
5. Water as substance has same secific heat. Specific does not depend on temperature of a material. SO it is false.
6. Since water has higher temperature so on adding heat its temperature change will be relatively less than alcohol. So water will be closer to its initial temperature.
7. This is false. Specific heat does not depend on desity of a liquid.
