- Q1At what temperature would there be absolutely no molecular motion in any object?0 degrees Kelvin0 degrees Farenheit0 Kelvin0 degrees Celsius30s
- Q2Why wear a coat in the cold?to keep your warmth next to youto keep the cold air off of youto let any warmth there might be come in contact with youto let your coldness escape leaving only warmth behind45s
- Q3How much thermal energy must be absorbed by 400g of water to raise its temperature by 15 degrees Celsius? The specific heat of water is 4.16 J/g·C. a. 39000 J b. 3000 J c. 375 J d. 25 J24,960 J4.16 J72 J1,442 J120s
- Q4How does thermal expansion work in a thermometer?The molecules undergo fission and increase the volume of the liquid.The number of molecules in the thermometer liquid change to count the degrees.The molecules increase in volume as they gain energy and get warmer.The molecules move further apart as they gain energy and get warmer.45s
- Q5Why are water molecules able to change from the liquid state to the gas state when energy is added?The energy added makes the molecules move more freely resulting in a plasma.The energy added makes the molecules move more quickly resulting in condensation.The energy added makes the molecules move more quickly, allowing them to break free resulting in evaporation or boiling.They can't. The energy added helps them to stay together.45s
- Q6What happens when you put a warm soda into the refrigerator?Heat transfer depends on the temperature.The warm soda gives it heat to the fridge.The fridge gives its heat to the soda.Heat always transfers from cold to hot.30s
- Q7Which type of spoon do you NOT want to use to stir boiling soup while it’s cooking on the stove?A metal spoon because it’s an insulatorA wooden spoon because it’s an insulator.A metal spoon because it’s a conductor.A wooden spoon because it’s a conductor.30s
- Q8You're always cold at night. You have the choice to sleep in the basement or the attic. To stay warmer, which should you choose?The attic because of conduction.The basement because of conduction.The attic because of convection.The basement because of convection.30s
- Q9Why is the metal portion of your car’s seat belt burn you more easily than the fabric/cloth?The metal is a higher temperature.The fabric is a lower temperature.The fabric is a conductor and transfers heat to you quickly.The metal is a conductor and transfers heat to you quickly.30s
- Q10How does the energy on Earth from the Sun get here?heat capacityconvectionradiationconduction30s
- Q11True or false? The lower specific heat an object has, the faster it's temperature will rise.FalseTrue30s
- Q12True or false? Concrete gets hotter faster than water because concrete has a LOWER specific heat capacity.TrueFalse30s
- Q13How many joules of heat are needed to raise the temperature of 30.0 g of aluminum from 40°C to 67°C, if the specific heat of aluminum is 0.90 J/g°C?7,290 J729 J7.29 JAll the joules120s
- Q14What type of heat transfer is pictured?Your faceConductionConvectionRadiation30s
- Q15What will happen to the molecules in the stick?The molecules will move faster and spread out as they gain energy due to convection.The molecules will move faster and spread out as they gain energy due to conduction.The molecules will move faster and get bigger as they gain energy due to conduction.The molecules will move faster and get bigger as they gain energy due to convection.60s
