Question

How many degrees Celsius is the difference between frozen food at 10 ⁰C below zero and boiling water at 100 ⁰C

Answer 1

Answer:

Raising the temperature of 10.0 g of water from 10.0 °C to 20.0 °C requires 100.0 cal of energy, while raising the temperature of 10.0 g of aluminum from 10.0 °C to 20.0 °C requires 22 cal..

Step-by-step explanation:

Raising the temperature of 10.0 g of water from 10.0 °C to 20.0 °C requires 100.0 cal of energy, while raising the temperature of 10.0 g of aluminum from 10.0 °C to 20.0 °C requires 22 cal. More calories are required to heat the water because A) water is a liquid and aluminum is a solid at 10.0 °C. B)

Here is your answer!

Answer 2

Concept:

Celsius is an unit to measure the temperature of any body or particle.

Besides Celsius, there are many units to measure temperature like Fahrenheit, Kelvin etc.

Given:

The frozon food is of $10^\circ\text{C}$ below zero and the boiling water is of $100^\circ\text{C}$.

To Find:

The Celsius difference between frozen food and boiling water.

Solution:

Frozen food is of $10^\circ\text{C}$ below zero.

So the temperature of frozen food is$=0-10^\circ=-10^\circ\text{C}$

The temperature of boiling water is $=100^\circ\text{C}$

Hence the celsius difference between frozen food and boiling water is given by $=100^\circ-(-10^\circ)=100^\circ+10^\circ=110^\circ\text{C}$

Hence $\mathbf{110^\circ\text{C}}$ is the difference between frozen food at $\mathbf{10^\circ\text{C}}$ below zero and boiling water at $\mathbf{100^\circ\text{C}}$.
