1) -29.27°F
239.1K
2)28.333°C
301.483K
3)50°C is greater
1). Given:
Boiling point of chlorine = -34 ° C
To Find:
Temperature in Fahrenheit (° F) = ?
Temperature in Kelvin = ?
Step-wise solution:
To convert the temperature in ° F when it is given in ° C apply following formula:
° F(temp) = [(9 ÷ 5) ° C (temp)] + 32
° F (temp) = [(9 ÷ 5) -34] + 32)
° F (temp) = (1.8) (- 34) + 32
° F (temp) = - 61. 2 + 32
° F (temp) = - 29.2
Hence, the temperature in Fahrenheit scale is - 29.2 °.
Now to convert the temperature in Kelvin when it is given in ° C apply formula as below:
K (temp) = ° C + 273.15 (∵ 273.15 is considered absolute zero temperature at triple point of water)
K (temp) = -34 + 273.15
K (temp) = 239. 15
Hence the temperature in Kelvin scale is 239.15 K
2). Given:
Air temperature = 83 °F
To find:
Temperature in Celsius (° C) = ?
Temperature in Kelvin = ?
Step-wise solution:
To find the temperature in ° C when the temperature is given in ° F use the formula:
° C (temp) = (5 ÷ 9) ° F (temp) -32
° C (temp) = (5 ÷ 9) 83 - 32
° C (temp) = (5 ÷ 9) 51
° C (temp) = 0.55 × 51
° C (temp) = 28. 33
Hence, the temperature in Celsius scale is 28.33 °.
We know that temp in ° C = 28.33 ° from above calculation
Therefore to convert the temperature in Kelvin when it is given in ° C apply formula as below:
K (temp) = ° C + 273.15
K (temp) = 28. 33 + 273.15
K (temp) = 301.43
Hence the temperature in Kelvin scale is 301.43 K.
3. Given:
Temperature in celsius = 50 °C
Temperature in fahrenheit = 50 ° F
To find:
That 50 ° C or 50 ° F is greater =?
Step-wise solution:
To find which is greater we need to first convert either of the temperature in similar scale.
So let us covert 50 ° C into Fahrenheit scale.
Apply the formula:
° F(temp) = [(9 ÷ 5) ° C (temp)] + 32
° F (temp) = [(9 ÷ 5) 50] + 32
° F (temp) = (1.8) (50) + 32
° F (temp) = 90 + 32
° F (temp) = 122
Hence 50 ° C is equivalent to 122 ° F
Therefore ,
50 ° F < 122 ° F = 50 ° C
Therefore we can conclude that 50 °C is greater than 50 °F.
