Since 1mL=1cm^3 the wood would sink due to it being more dense. I.e. 0.95>0.88
An Exothermic reaction releases energy into the surroundings and so the products have more potential energy then the reactants. The enthalpy change is a negative value. Whereas, an endothermic reaction involves the absorption of energy into the system and so the reactants have more potential energy than the products. The enthalpy change is a positive value. This is clearly represented in energy profile diagrams.
H2O became a vapor when heated because thats the only one that can go back to its normal state, which is what a physical change is.
Molecules move more slowly in solids because there they are all very compact
Answer:
<h2>1 atm</h2>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we're finding the new pressure
We have
We have the final answer as
<h3>1 atm</h3>
