Heat is transferred when a substance changes phases. Substances can be made to change phases by fluctuating the temperature, the pressure, or both. I hope I could help!
Answer:
Vibrations
Explanation:
That is why when under water it sounds muffled and you cannot hear clearly.
For this problem, let's use the approach of dimensional analysis. This technique is done by cancelling out like units that appear both on the numerator and the denominator side. As a result, this technique will let you know that your final answer conforms to what parameter is asked. In this case, the final answer should be in kJ. We use the conversion: 1000 cal = 4.184 kJ The solution is as follows:
<span>6.95×10</span>⁵<span> cal * 4.184 kJ/1000 cal = 2,907.88 kJ</span>
