The amount of heat neededto raise 2.0 kg of a substance by 80 K is 33 kJ. What is the specific heat of
the substance?

Answers

Q = mcθ
 
Where Q = Amount of heat in J
             m = Mass of substance in kg
              θ  = Temperature rise in °C or K
              C = Specific heat capacity in J/kgK

From given data:
Q = 33 kJ = 33 000 J, m= 2.0 kg,   θ  = 80 K,   c = ?

33000 =  2 * c * 80
33000 = 160c
160c   = 33000
       c   =  33000/160 = 206.25

Therefore specific heat capacity is 206.25 J/kgK

Differentiate elastic potential energy and chemical potential energy​

Answers

Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.  

Chemical potential energy​​ is position of electrons in specific substance bonds that can be broken (energizes).

:

This stored energy is released and performs work when the elastic material reverts back to its original position. ... In comparison, chemical potential energy, is the energy released during the formation of chemical compounds.

An acorn with a mass of 0.0300 kilograms falls from a tree. What is its kinetic energy when it reaches a velocity of 5.00 m/s?

Answers

Kinetic energy = 1/2 (mass) x (speed squared).

KE = 1/2 (0.03) x (5 x 5) = 0.375 kilogram-meter squared / second squared = 0.375 Joule.
