A. Heat because it does not take up space.
Conduction
Convection
Radiation
Explanation:
The main types of heat transfer are heat transfer by conduction, convection and by radiation.
These forms of heat transfer has different modes of application.
- Conduction is a form of heat transfer in solids. It requires a material medium to dissipate. Here, heat flows from a hot end to a cold end.
- Convection is a form of heat transfer in fluids i.e liquids and gases. In convection, heat is transferred due to density differences between heated fluids.
- Radiation does not involve material medium. It uses the electromagnetic waves to dissipate heat.

Ch h,c c2 that’s all just add them up
Answer: 3.80 x 10^-4M
Explanation: I crawled so you could run :)
The heat is involved in the production of 5.0 mol of MgO is 180 Kj
calculation
2 Mg (s) +O2 → 2 MgO
From the equation above two moles of MgO is used therefore
72.3 is for 2 moles
that is 72.3 kj = 2moles
? = 5 moles
by cross multiplication
= 72.3 kj × 5/2 = 180 Kj
