Answer:
Mechanical energy is basically the energy of movement
For example, if I am running, im using Mechanical energy
The student would fill out the second row, stating that the volume increases as the temperature increases.
This phenomenon is in accordance with Charles's law, which states that for a fixed amount of gas at a constant pressure, the volume of the gas is directly proportional to the absolute temperature of the gas. All three of the gas laws are combined to form the ideal gas law.
Heat= mass * change in temperature* specific heat
specific heat=409 J/kg K
Answer:
spring, summer, fall, and winter
Answer : The heat required is, 1904 calories.
Explanation :
The process involved in this problem are :
The expression used will be:
![\Delta H=m\times \Delta H_{fusion}+[m\times c_{p,l}\times (T_{final}-T_{initial})]](https://tex.z-dn.net/?f=%5CDelta%20H%3Dm%5Ctimes%20%5CDelta%20H_%7Bfusion%7D%2B%5Bm%5Ctimes%20c_%7Bp%2Cl%7D%5Ctimes%20%28T_%7Bfinal%7D-T_%7Binitial%7D%29%5D)
where,
m = mass of ice = 17 g
= specific heat of liquid water = 
= enthalpy change for fusion = 
Now put all the given values in the above expression, we get:
![\Delta H=17g\times 80.0cal/g+[17g\times 1cal/g^oC\times (32.0-0)^oC]](https://tex.z-dn.net/?f=%5CDelta%20H%3D17g%5Ctimes%2080.0cal%2Fg%2B%5B17g%5Ctimes%201cal%2Fg%5EoC%5Ctimes%20%2832.0-0%29%5EoC%5D)
Therefore, the heat required is, 1904 calories.
