Question 4: [2 pts) Imagine you add a certain amount of energy to a known amount of a liquid in a perfectly insulated cup. You measure the change in temperature. Then you decide to alter the experiment in several ways. For each of the alterations listed below, state whether the change in temperature will be larger, smaller, or the same as that measured before the alteration. Explain each answer briefly. Item 1 is answered as an example. 1. Add more heat: Larszer (temperature change, because the change in temperature is directly proportionavto the amount ofheat added 2. Heat for a longer time but add the same amount of heat: 3. Use more liquid in the cup 4. Increase the temperature outside of the cup: 5. Start with warmer liquid 6. Change to an equal mass of a liquid with a larger specific heat capacity: 7. Use the same volume of denser liquid with the same specific heat capacity:

Explanation / Answer

1. IF MORE HEAT ADDED

the temperature will be more due to more thermal energy

2. HEAT FOR LONGER TIME

if time is more then it will absorb more heat for longer time and temperature will be more

3. USE MORE LIQUID

since more liquid is used so its temperature will be lesser

4. INCREASE THE TEMPERATURE OUTSIDE

the sorrounding condition will increase the temperature of liquid

5 START WITH WARMER LIQUID

more warmer liqiud will increase more temperature

6> LARGER HEAT CAPACITY LIQUID

If heat acapcity is more then temperature of liquid will be lesses

7. SAME VOLUME OF DENSER LIQUID

then the mass will be more hence temperature will be LESS
