Solved the first three questions, please post one more question to get the remaining answers problem

Q2) Determine which temperature is hotter

a) 200 K and 300 R

Temperature on Renkin Scale = 9/5 * (Temperature on Kelvin Scale)

=> 9/5 * 200

=> 360 R

Hence 200K is equal to 360 R, therefore we get that 200K is more hotter than 300 R

b) -150 C or -225F

Temperature in Celsius Scale = 5/9 * (Temperature in Fahrneheit Scale - 32)

=> 5/9 * (-225-32)

=> 5/9 * (-257)

=> -142.77 Celsius

Hence -225F is more hottern than -150 C

5) The SI units will be equal to Kg/m^3

According to conversion ratio,

1 Kg/m^3 = 0.06248 lb/ft^3

Hence converting it into SI units, we get

39.3/0.06248 = 629.001 Kg/m^3

17)

1 Btu/hr = 0.29307107 Joules/second [ Conversion Factor]

Hence converting 157 J/s to Btu/hr, we get

Equivalent in Btu/h = 157/0.29307107 = 553.706 Btu/h
