Question

the average january temperature for helsinki,finald is 21.0 F and the average july temperature is 62.2 F. how much hotter is it in july (Tjul-Tjan) in the rankine scale?

what is the difference between july and january temperatures in the celsius scale?

what is the difference between july and januare in the kelvin scale?

Answer 1

lets convert both temperature in all scale:

convert Fahrenheit to celsius Scale

Given:

F = 21.0 oF

use:

C = (F - 32) * 5/9

C = (21.0 - 32) * 5/9

C = -6.11

convert Fahrenheit to Kelvin Scale

Given:

F = 21.0 oF

use:

K = (F - 32) * 5/9 + 273.15

K = (21.0 - 32) * 5/9 + 273.15

K = 267.04

convert Fahrenheit to Rankine Scale

Given:

F = 21.0 oF

use:

R = F + 459.67

R = 21.0 + 459.67

R = 480.67

convert Fahrenheit to celsius Scale

Given:

F = 62.2 oF

use:

C = (F - 32) * 5/9

C = (62.2 - 32) * 5/9

C = 16.78

convert Fahrenheit to Kelvin Scale

Given:

F = 62.2 oF

use:

K = (F - 32) * 5/9 + 273.15

K = (62.2 - 32) * 5/9 + 273.15

K = 289.93

convert Fahrenheit to Rankine Scale

Given:

F = 62.2 oF

use:

R = F + 459.67

R = 62.2 + 459.67

R = 521.87

=================================================

so we have:

21.0 F = -6.11 oC = 267.04 K = 480.67 R

62.2 F = 16.78 oC = 289.93 K = 521.97 R

1)

difference in R scale = 521.97 - 480.67 = 41.3 R

2)

difference in C scale = 16.78 - (-6.11) = 22.9 oC

3)

difference in K scale = 289.93 - 267.04 = 22.9 K
