Question

If an object with an initial temperature of 300 K increases its temperature by 1°C every minute, by how many degrees Fahrenheit will its temperature have increased in 10 minutes? (A) 6°F (B) 10°F (C) 18°F (D) 30°F

Answer 1

Answer: B) $10^{\circ}K$

Explanation:

Let x be the number of minutes in which the temperature is increased.

Given: The initial temperature : $C=300^{\circ} K$

The constant rate of increase in each minute :  $m=1^{\circ} K$

Since the situation follows a linear growth, then the increase in temperature (in Kelvin) after x minutes is given by the expression :-

$mx$

Then, the increase in temperature (in Kelvin) after 10 minutes:-

$1\times10=10^{\circ}K$
