(a)
Whether the statement is true or false.
(a)

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.
(b)

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.

- A spectra is a graph that has amplitude on the Y-axis and frequency on the X-axis. A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced. If the Fo of a sound is 125 Hz, please sketch a spectra (amplitude on the Y axis, frequency on the X axis) of the harmonic series up to the 4th harmonic. Include actual values on Y and X axis.arrow_forwardSketch a sign wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forwardSketch a sine wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forward
