UNIT AND DIMENSIONS

Take the values of (prop) from table 20.2.
A pendulum clock of time period 2s gives the correct time at 30∘C. The pendulum is made of iron. How many seconds will it lose or gain per day when the temperature falls tp 0∘C? αFe=1.2×10−5(.∘C)−1.

From the graph for an ideal gas, state whether m1orm2 is greater. .

An ideal diatomic gas with CV=5R2 occupies a volume (Vi at a pressure (Pi. The gas undergoes a process in which the pressure is proportional to the volume. At the end of the process, it is found that the rms speed of the gas molecules has doubles from its initial value. Determine the amount of energy transferred to the gas by heat.

A sample of an ideal gas occupies a volume V at pressure P and absolute temperature T. The masss of each molecule is m, then the density of the gas is

Assertion Velocity , volume and acceleration can be taken as fundemental quantities because
Reason: All the three are independent from each other .

What is the value of.
(a) 0∘F in Celsius scale ?
(b) (0 K) on fahrenheit scale ?

The Kelvin scale temperature is 0 K. What is the corresponding Celsius scale temperature ?

0 K ताप का मान (i) सेल्सियस पैमाने पर, (ii) फारेनहाइट पैमाने पर ज्ञात कीजिये।

किस ताप पर- (A) सेल्सियस तथा फारेनहाइट पैमाने का पाठ्यांक बराबर होगा। (B) फारेनहाइट तथा केल्विन पैमाने का पाठ्यांक बराबर होगा। (C ) केल्विन तथा सेल्सियस पैमाने का पाठ्यांक बराबर होगा?

(i) 0∘F का सेल्सियस पैमाने पर, (ii) 0 K का फारेनहाइट पैमाने पर मान क्या है?

A measured temperature on Fahrenheit scale is 200∘F. What will this reading be on clesius scale?

Assertion. The size of a degree on Fahrenheit scale is smaller than that on celsius scale. Reason. When temperature on celsius scale reads 0^(@) , it reads 32^(@) on Fahrenheit scale.

A measured temperature on Fahrenheit scale is 200°F. What will this reading be on Celsius scale ?
