The temperature of a body rises by 2°C.What is the corresponding rise on the Fahrenheit and Kelvin scales? |
|
Answer» (a) Since 100 divisions on Celsius scale =180 divisions on the Fahrenheit scale 2 division on Celsius scale ∴ 2 division on Celsius scale = 1.80 / 1.00 × 2 = 3.6 divisions in the Fahrenheit scale. For 2°C rise corresponding rise in Fahrenheit = 3.6 F (b) Since 100 divisions in the Celsius scale = 100 divisions in the Kelvin scale 2 division on Celsius scale = 100 / 100 × 2 = 2 division on Kelvin scale For 2°C rise corresponding rise in Kelvin is 2 K. Given : TC = 2° c TF = ? Tk = ? Using formula In farhrenhiet TF = \(\cfrac95\) TC + 32 TF = \(\cfrac95\) x 2 + 32 TF = 3.6 + 32 TF = 35.6° F In kelvin value TK = TC + 273 TK = 2° + 273 TK = 275° K |
