Answer:
3.58J/g°C is the specific heat of the metal
Explanation:
The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:
Q = S*ΔT*m
<em>Where Q is energy = 1362J</em>
<em>S is specific heat of the material</em>
<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>
<em>And m is the mass of the material = 15.2g</em>
Replacing:
S = Q / ΔT*m
S = 1362J / 25°C*15.2g
<h3>3.58J/g°C is the specific heat of the metal</h3>
Answer:
The answer for number one is .A
The answer for number two is heat rises
Explanation:
Answer: Option (A) is the correct answer.
Explanation:
When the questions are technical and may require some research from the interviewee then an interviewer want to provide the interviewee a list of questions before the interview.
As only in this case, interviewer wants the interviewee to take some time in order to think about the particular question and then answer it appropriately.
As if there is no list of questions then there are changes that interviewee will forget about some useful point which is important to keep in mind before answering.
