Question

A piece of metal is heated to increase its temperature from $5^{\circ }C$ to ${15}^{\circ }C$. The increase in temperature expressed in $K$ and ${}^{\circ }F$ are respectively.

• A. $10K,{18}^{\circ }F$
• B. $283K,{50}^{\circ }F$
• C. $18K,{10}^{\circ }F$
• D. $50K,{283}^{\circ }F$

Answer 1

The correct option is A $10K,{18}^{\circ }F$

$K=273.16+CF=\frac{9C}{5}+32dK=dCdF=\frac{9}{5}dC$

A/Q, $dC=15-5=10\therefore dK=10K,dF=\frac{9}{5}\times 10=18°F$
