Explanation of Solution
Introduction:
Zeroth law of
According to Zeroth law of thermodynamic when two systems or bodies are in thermal equilibrium with the third system then they will be in thermal equilibrium with each other. The system is in Thermal equilibrium when the pressure, temperature and volume do not change with time.
Conclusion:
If the two systems A, Bare in thermal equilibrium with the third system C, then the two systemsA and B are also in thermal equilibrium with each other. Thus, the given statement is false.
(b)
Whether the statement is true or false.

Explanation of Solution
Introduction:
The Fahrenheit is the unit to measure the temperature. The symbol of Fahrenheit is
Both are the unit to measure temperature and they are almost similar. In many countries the Celsius is accepted as the standard unit whereas in the United States Fahrenheit is the standard unit to measure temperature. The Celsius and Fahrenheit scale differ in the number of intervals between the ice point and the boiling point.
Conclusion:
The number of interval between the ice point and the boiling point is different for the Celsius and the Fahrenheit scale. Thus, the given statement is false.
(c)
Whether the statement is true or false.
(c)
Explanation of Solution
Introduction:
The kelvin is the unit to measure temperature it is based on absolute scale means absolute zero is at zero kelvin and negative temperature are not in kelvin scale. The size of a unit Celsius is same the size of a unit kelvin that is the change in temperature of one Celsius is equal to the change in temperature of one kelvin.
The absolute zero in Celsius is at
The conversion factor of Celsius to kelvin is:
Here,
Conclusion:
The size of a unit Celsius is same the size of a unit kelvin that is the change in temperature of one Celsius is equal to the change in temperature of one kelvin. Thus, the given statement is true.

- One of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?arrow_forwardAn aluminum rod 0.500 m in length and with a cross-sectional area of 2.50 cm2 is inserted into a thermally insulated vessel containing liquid helium at 4.20 K. The rod is initially at 300 K. (a) If one-half of the rod is inserted into the helium, how many liters of helium boil off by the time the inserted half cools to 4.20 K? Assume the upper half does not yet cool. (b) If the circular surface of the upper end of the rod is maintained at 300 K, what is the approximate boil-off rate of liquid helium in liters per second after the lower half has reached 4.20 K? (Aluminum has thermal conductivity of 3 100 W/m K at 4.20 K; ignore its temperature variation. The density of liquid helium is 125 kg/m3.)arrow_forwardThe height of the Washington Monument is measured to be 170.00 m on a day when the temperature is 35.0 .
