Question: Which is larger, 1 C掳 or 1 F? Explain why.

Short Answer

Expert verified

1 C掳 is larger than 1 F掳.

Step by step solution

01

Understanding of temperature

The term "temperature" may be defined as the thermodynamical characteristic of a particular system, determining whether a body is cool or warm.

02

Relationship between the 1 C° and 1 F°

One hundred divisions on the centigrade scale are equal to the 180 divisions on the Fahrenheit scale. Therefore, the relationship between the centigrade and Fahrenheit can be written as follows:

\(\begin{array}{c}1{\rm{^\circ C}} = \frac{{180}}{{100}}\;{\rm{^\circ F}}\\1{\rm{^\circ C}} = \frac{9}{5}{\rm{^\circ F}}\\{\rm{1^\circ C}} = 1.8{\rm{^\circ F}}\end{array}\)

From the above relation, it is clear that the centigrade scale is larger than the Fahrenheit scale.

Question 36:(III) A sealed test tube traps of air at a pressure of 1.00 atm and temperature of 18掳C. The test tube鈥檚 stopper has a diameter of 1.50 cm and will 鈥減op off鈥� the test tube if a net upward force of 10.0 N is applied to it. To what temperature would you have to heat the trapped air in order to 鈥減op off鈥� the stopper? Assume the air surrounding the test tube is always at a pressure of 1.00 atm.

(III) Air that is at its dew point of 5掳C is drawn into a building where it is heated to 22掳C. What will be the relative humidity at this temperature? Assume constant pressure of 1.0 atm. Take into account the expansion of the air.

(II) A helium-filled balloon escapes a child鈥檚 hand at sea level and 20.0掳C. When it reaches an altitude of 3600 m, where the temperature is 5.0掳C and the pressure only 0.68 atm, how will its volume compare to that at sea level?

(II) To what temperature would you have to heat a brass rod for it to be 1.5% longer than it is at 25掳C?

Question:(II) An aluminum bar has the desired length when at 12掳C. How much stress is required to keep it at this length if the temperature increases to 35掳C? (See Table 9鈥�1.)
