Question

On Reaumer scale of temperature
melting point of ice and the boiling
point of water are taken as Oºr and
80°R respectively. The freezing point
and boiling point of mercury on
Celsius scale are 39°C and 367°C
respectively. Express these
temperature on Kelvin scale.
OK, 273 K
41 K, 290K
312 K, 640 K
O 71K, 293.6K

Answer 1

Answer:

Answer

Correct option is

C

31.2R, 293.6R

In Reaumer scale we take

0C

0

=0R

100C

0

=80R

1C

0

=

100

80

=0.8R

if we convert the celcius degree to R

⇒39C

0

=0.8×39R=31.1R

⇒367C

0

=0.8×367=293.6R

hence option C is correct

Answer 2

Explanation:

• 0° =
• 100 ° =80
• 1 °=80 100 = 0.8 .
• 39 ° = 0.8 ×39 = 31.1
• 367° = 0.8 ×367 = 293.6
