Question

Explain the difference between heat and temperature. Does 1 L of water at 65°F have more, less, or the same quantity of energy as 1 L of water at 65°C?

Answer 1

Solution

$\text{Temperature}$ is a $\text{relative measurement}$ of how cold/warm a body is when compared to another body.

$\text{Heat}$ is defined as $\text{energy}$ which flows form the object that has $\text{higher temperature}$ to the object that has $\text{lower temperature}$.

In order to compare energy of water that is at 65 degrees Celsius and the water that is at 65 degrees Fahrenheit we have to $\text{convert one of the units to another.}$ We will convert degrees Fahrenheit to degrees Celsius.

$\text{T(°C) = (T(°F) - 32) *5/9}$

T(°C) = (65(°F) - 32) *5/9

T(°C) = 18,333°C

So 65 degrees Fahrenheit is $\text{18,333 degrees Celsius.}$

Since 65 degrees Celsius is $\text{higher temperature}$ than 65 degrees Fahrenheit we can conclude that $\text{water at 65 degrees Celsius has more energy.}$

Therefore,

$\text{Temperature}$ is a $\text{relative measurement}$ of how cold/warm a body is when compared to another body.

$\text{Heat}$ is defined as $\text{energy}$ which flows form the object that has $\text{higher temperature}$ to the object that has $\text{lower temperature}$.

Since 65 degrees Celsius is $\text{higher temperature}$ than 65 degrees Fahrenheit we can conclude that $\text{water at 65 degrees Celsius has more energy.}$
