Question

On the "New" temperature scale, water boils at ${500}^{\circ }$ and freezes at ${300}^{\circ }$. Under standard conditions, ${38}^{\circ }$ Celsius corresponds to what temperature on the "New" scale?

• A. ${356}^{\circ }New$
• B. ${338}^{\circ }New$
• C. ${319}^{\circ }New$
• D. ${438}^{\circ }New$
• E. ${376}^{\circ }New$

Answer 1

Answer: (E)

${376}^{\circ }New$

Water freezes at $0^{o}C$ and boils at ${100}^{o}C$ according to Celsius scale.

$\therefore$ $0^{o}C$ corresponds to ${300}^o$ $New$ whereas${100}^{o}C$ corresponds to ${500}^o$ $New$.

$⟹$ $\Delta 1^{o}C=\Delta 2^o$ $New$

$\therefore$ ${38}^{o}C=300+38\times 2={376}^o$ $New$
