Question

an ice cube absorbs 353 cal of energy from its surroundings. how many joules of energy is this? ? joules

Explanation:

Step1: Recall the conversion factor

We know that \( 1 \text{ cal} = 4.184 \text{ J} \).

Step2: Calculate the energy in joules

To convert calories to joules, we multiply the number of calories by the conversion factor. So, for \( 353 \text{ cal} \), the energy in joules \( E \) is given by:
\( E = 353 \times 4.184 \)
Calculating this, we get \( 353\times4.184 = 1477.952 \)

Answer:

\( 1477.952 \) (or approximately \( 1478 \) depending on significant figures, but using the exact conversion here gives \( 1477.952 \))
