Consider a system whose temperature is 18°C. Express this temperature in R, K, and °F.
zvonat [6]

Answer:

In Rankine 524.07°R

In kelvin 291 K

In Fahrenheit 64.4°F  

Explanation:

We have given temperature 18°C

We have to convert this into Rankine R

From Celsius to Rankine we know that  T(R)=(T_{C}+273.15)\frac{9}{5}

We have to convert 18°C

So T(R)=(18+273.15)\frac{9}{5}=524.07^{\circ}R

Conversion from Celsius to kelvin

T(K)=(T_{C}+273)

We have to convert 18°C

T(K)=(18+273)=291K

Conversion of Celsius to Fahrenheit

T(F)=T_{C}\times \frac{9}{5}+32=64.4^{\circ}F
