an ice cube absorbs 353 cal of energy from its surroundings. how many joules of energy is this? ? joules
Answer
Explanation:
Step1: Recall the conversion factor
We know that ( 1 \text{ cal} = 4.184 \text{ J} ) (this is the conversion factor between calories and joules).
Step2: Multiply the number of calories by the conversion factor
We have ( 353 \text{ cal} ), so to convert to joules, we calculate ( 353 \times 4.184 ). ( 353\times4.184 = 353\times(4 + 0.184)=353\times4+353\times0.184 = 1412+64.952 = 1476.952 )
Answer:
( 1476.952 ) (or approximately ( 1477 ) depending on significant figures or rounding requirements)
