Distinguish between heat and temperature. Compare definitions and units of measurements.

Question 2

A cylindrical metal wire at room temperature is carrying electric current between its ends. One end is at potential VA = 50 V, and the other end is at potential VB = 0 V. Rank the following actions in terms of the change that each one separately would produce in the current from the greatest increase to the greatest decrease. In your ranking, note any cases of equality.
   (a) Make VA = 150 V with VB = 0 V.
   (b) Adjust VA to triple the power with which the wire converts electrically transmitted energy into internal energy.
   (c) Double the radius of the wire.
   (d) Double the length of the wire.
   (e) Double the Celsius temperature of the wire.

  1.b > c > a > e > d
  2.d > a > c > b > e
  3.c > a > b> e > d
  4.a > c > d > e > b
  5.None of these.

Answer to Question 1

Heat is energy in transit and is measured in calories or British thermal units.
Temperature is a measurement of the hotness or coldness of an object, and
temperature is proportional to the average kinetic energy of the molecules.
Temperature is measured in degrees Celsius or degrees Fahrenheit.
