Answer:
2000J
Explanation:
Given parameters:
Heat of fusion = 80J/g
Mass of substance = 25g
Unknown:
Amount of energy required to melt the given mass = ?
Solution:
To solve this problem, the amount of energy required to melt the substance is given as;
H = m L
m is the mass
L is the heat of fusion
Insert the given parameters and solve;
H = 25 x 80 = 2000J
Microscope . Small structure of the cells can look into for a microscope... This part regulates the amount of light on the specimen
3 millimeters since it is the smallest of the four and dimes are very thin
Convection is the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock (rheid). Convection takes place through advection, diffusion or both.
Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place. Diffusion of heat takes place in rigid solids, but that is called heat conduction. Convection, however, can take place in soft solids or mixtures where solid particles can move past each other.
Hope this helps you if not my bad.
