Question

Four beakers A, B, C and D with specific temperatures are shown. Which of the beakers are at equivalent temperature?

• A. A and C
• B. C and D
• C. A and B
• D. B and C

Answer 1

The correct option is D B and C

Kelvin $\left(K\right)$ and degree Celcius ${(}^{0}C)$ are units for measuring temperature.
Where, $\left(0{}^{0}C\right)$ = $\left(273K\right)$
Hence,
$t{}^{\circ }C$ = $tK$ $-273$
For beaker A:
$t{}^{\circ }C$ = $300-273$ = $27{}^{\circ }C$

For beaker B:
$20{}^{\circ }C$

For beaker C:
$293K$ = $293-273$ = $20{}^{\circ }C$

For beaker D:
$0K=0-273$ = $-273{}^{\circ }C$
Thus, temperature of beakers B and C are same.
