Answer:
4.occupy a definite volume while taking the shape of their container.
Explanation:
Since the particles in a liquid are quite close together (not as close as a solid) they have a definete volume, and the particles are still able to move around as they wish they have no definite shape and take upon the shape of the container they are placed in.
Answer:
700 calories
Explanation:
Using the formula below:
Q = m × c × ∆T
Where;
Q = amount of heat required (calories)
m = mass of substance (g)
c = specific heat of substance (cal/g°C)
∆T = change in temperature (°C)
According to this question, the following information was provided;
Q = ?
m = 20g
c = 1.0 cal/g °C
∆T = 40°C - 5°C = 35°C
Using the formula; Q = m × c × ∆T
Q = 20 × 1 × 35
Q = 700 calories
Hence, 700 cal of heat energy is needed to raise 20 g of H2O from 5°C to 40°C.
Answer:
One way is to add or remove a product or a reactant in a chemical reaction at equilibrium. When additional reactant is added, the equilibrium shifts to reduce this stress: it makes more product. When additional product is added, the equilibrium shifts to reactants to reduce the stress. :)
Explanation:I am not sure how to use data on here :(
Inherited it from his grandfather
Because of pollution from factories and other activities that release harmful gases into the air
