Question

name: joel t date: period: calculate the number of calories in a food sample that raised the temperature of 25g of water 40 degrees q=mcδt

Explanation:

Step1: Identify values

Mass \( m = 25\,\text{g} \), specific heat of water \( c = 1\,\text{cal/g}^\circ\text{C} \), temperature change \( \Delta T = 40^\circ\text{C} \).

Step2: Apply formula \( Q = mc\Delta T \)

Substitute values: \( Q = 25 \times 1 \times 40 \).

Step3: Calculate

\( 25 \times 40 = 1000 \).

Answer:

The number of Calories is \( 1000 \) (or \( 1\,\text{kcal} \)).
