The label on a pressurized can of spray disinfectant warns against heating the can above 130 degree fahrenheit . What are the co

Leviafan [203]

Answer : The temperature in degree Celsius and Kelvin is, $54.44^oC\text{ and }327.59K$ respectively.

Explanation :

The conversion used for the temperature from Fahrenheit to degree Celsius is:

$^oC=(^oF-32)\times \frac{5}{9}$

where,

$^oF$ = temperature in Fahrenheit

$^oC$ = temperature in centigrade

The conversion used for the temperature from degree Celsius to Kelvin is:

$K=273.15+^oC$

where,

$K$ = temperature in Kelvin

$^oC$ = temperature in centigrade

As we are given the temperature in Fahrenheit is, 130

Now we have to determine the temperature in degree Celsius.

$^oC=(^oF-32)\times \frac{5}{9}$

$^oC=(130^oF-32)\times \frac{5}{9}$

$^oC=54.44$

Now we have to determine the temperature in Kelvin.

$K=273.15+^oC$

$K=273.15+(54.44^oC)$

$K=327.59$

Therefore, the temperature in degree Celsius and Kelvin are, $54.44^oC\text{ and }327.59K$
