Answer:
1. conduction 5. heat from the air is absorbed by ice cubes is conduction 6. a hot horseshoe transfers heat to the tongs is conduction. 8. a bowl of oatmeal cools is convection 9. water is warmed over a fire is convection/radiation 10. a spoon gets warmer after sitting in a bowl of soup is conduction.
Explanation:
the last two i don't know sorry but i give u the answers to the others:)
The basalt is a sign that the Moon once had magma at its surface because the basalt is a type of rock that forms directly from the cooling off of the magma. The basalt is part of the igneous type of rocks, which are the type of rocks that form from the cooling of the magma, be it on the surface or inside the ground, so having basalt on the Moon is a sure sign that our natural satellite once had magma on it.
Answer:
true
Explanation:
I think it is true but im uncertain
Answer:
B.the velocity for the forward reaction equal that of the reverse reaction
Explanation:
A state of rest or motion of a system is described as equilibrium.
For a system to be in equilibrium, the following conditions must be met:
1. It must be involved in reversible chemical process no matter how small the extent of the reversibility.
2. The rate of forward process is equal to the rate of backward or reverse process.
3. The system must be closed.
4. There is no change in the concentration of each of the species in equilibrium with respect to time. There must be a constancy of concentration of each species in the equilibrium process.
When we change any of the conditions of equilibrium, the Le Chatelier's principle comes into play.
The principle states that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
It is a mixture of a variety of substances
