(a) The boiling point of acetylene is
(b) The bailing point of helium is 4 K. Below what temperature, in degrees Celsius, is helium a liquid?
(c) Human body temperature is normally
(a)
Interpretation:
The temperature in terms of Kelvin and degree Celcius at which acetylene exists as a liquid state.
Explanation of Solution
The conversion of temperature from degree Celsius to degree Fahrenheit can be done using the following relation:
Here,
The conversion of temperature from degree Celsius to Kelvin can be done using the following relation:
Here,
The conversion of temperature from degree Fahrenheit to degree Celsius can be done using the following relation:
Here,
The temperature ( in
The boiling point of acetylene is given to be
Therefore, the temperature at which the acetylene exists as a liquid, in terms of kelvin is found to be
The temperature (in
The boiling point of acetylene is given to be
Therefore, the temperature at which the acetylene exists as a liquid, in terms of degree Fahrenheit is found to be
(b)
Interpretation:
The temperature in terms of degree Celcius below which helium exits in a liquid state.
Explanation of Solution
The temperature ( in
Here,
The boiling point of helium is given to be
Therefore, the temperature at which helium exists as a liquid, in terms of Kelvin, is found to be
(c)
Interpretation:
The normal temperature of the human body in terms of degree Celsius and kelvin.
Explanation of Solution
The temperature (in
The normal body temperature of the human body is
Therefore, the normal temperature of the human body in degree Celsius is found to be
The normal body temperature (in
Here,
The normal body temperature of the human body is
Therefore, the normal temperature of the human body in kelvin is found to be

INTRODUCTION TO CHEMISTRY-ACCESS
- A cylindrical bar was found at the bottom of a storage tank of unknown composition. The material had a diameter of 8 mm, a length of 62 cm and a mass of 0.018 kg. What is the density of this material in g/mL? The volume of a cylinder is given by V = πr^2h.arrow_forwardA sample of nitrogen gas, N2, travels 17.0 cm in 4.5 minutes. How long in minutes would it take chlorine gas, Cl2, to travel a distance of 17.0 cm under the same conditions?arrow_forwardWhat is the volume, in cubic centimeters (cm^3) of 1.00 kilograms of gold?arrow_forward
- Which piece of equipment would you use to measure 7.10 mL of CuSO4 (aq)?arrow_forwardA cylindrical glass tube 12.7 cm in length is filled withmercury (density = 13.6 g/mL). The mass of mercuryneeded to fill the tube is 105.5 g. Calculate the innerdiameter of the tube (volume of a cylinder of radius rand length h is V = πr2h).arrow_forwardThe German chemist Fritz Haber proposed paying off the reparations imposed against Germany after World War I by extracting gold from seawater. Given the following data, what was the dollar amount of the gold that could have been extracted from 3.0 m3 of seawater? The price of gold at the time was $0.68 per gram of gold. Gold occurs in seawater to the extent of 5.15 x 1011 atoms per gram of seawater. The density of seawater is 1.03 g/cm3.arrow_forward
- Suppose that instead of using the cylindrical rod of Example 1-2 to prepare a 1.000 kgmass we were to use a solid spherical ball of copper What must be the radius of this ball?arrow_forwardAt 25 C, the density of water is 0.997 g/cm3, whereas the density of ice at 10 C is 0.917 g/cm3. (a) If a soft-drink can (volume = 250. mL) is filled completely with pure water at 25 C and then frozen at - 10 C, what volume does the ice occupy? (b) Can the ice be contained within the can?arrow_forwardIn Active Example 3-29 you calculated that you would have to work six weeks to earn enough money to buy a 1082.49 television. You would be working five shifts of four hours each at 9.25/hr. But, alas, when you received your first pay check, you found that exactly 23 of your earnings had been withheld for social security, federal and state income taxes, and workers compensation insurance. Taking these into account, how many weeks will it take to earn the 1082.49?arrow_forward
