Answer:
The correct option is:
A) by direct or indirect contact between objects at different temperatures
Explanation:
Heat can be transferred in three different methods:
Conduction, Convection and Radiation
Conduction is heat transfer through direct contact between substances at different temperatures.
Convection is the heat transfer which takes place through air currents.
Radiation is the heat transfer that does not require contact between two objects.
Hence, heat transfer can take place through direct or indirect contact between objects at different temperatures.
Answer:
Density, 
Explanation:
It is given that, placing a sample of iron (II) oxide into a graduated cylinder makes the water volume increase 12.0 mL.
It means that the volume of the sample is 12 mL
The weight of the sample is 76.6 g
We need to find the density of the sample.
12 mL = 12 cm³
The formula of density is given by :

So, the density of the sample is
.

Answer:
The mass of the forest comes from carbon and carbon is retrieved from carbon-dioxide that trees used during the process of photosynthesis. In the process of photosynthesis, carbon-dioxide is utilised from the atmosphere by trees and release oxygen and ATP.
When the forest burns the mass again releases to atmosphere in the form of carbon which causes air pollution and increases carbon content in the atmosphere.
