Ben wants to test whether the material used to make a disposable cup affects the amount of thermal energy transferred to a person’s hand. He investigates by carefully pouring the same volume of 90°C water into a foam cup and into a paper cup.
Which additional step in the investigation will help Ben determine which material reduces thermal energy (heat) transfer to the hand of a person holding the cup?
Multiple choice question.
A)
Measure the outside surface temperature of each cup after 10 minutes.
B)
Stir the water in each cup for 10 minutes before measuring its temperature.
C)
Vary the amount of water held by each cup before measuring its temperature.
D)
Measure the outside surface temperature of each cup after placing each on a different surface.
Answers
Answer:
A) Measure the cup outside surface temperature of each cup after 10 mins will help ben determine which material reduces thermal energy (heat) transfer to the hand of a person holding the cup
Explanation:
Thermal energy, commonly known as the internal energy, is the energy connected to microscopic types of energy in thermodynamics. Depending on the capacity of the system or the amount of chemical it contains, it is a sizable amount. The joule is the SI unit for thermal energy (J)
An object's internal temperature, which is caused by thermal energy, can be measured, for instance, in degrees Centigrade or Fahrenheit using a thermometer.
The Temperature which is measured increases in proportion to how quickly the particles are moving through an object or system.
Hence,
To measure if paper cup or foam cup reduces thermal energy (heat) transfer to the hand of a person holding the cup, ben should measure the cup outside surface temperature of each cup after 10 mins
