Because mass is neither created nor destroyed, so the wax can not just disappear.
We are asked to give two possible explanation when bubbles are formed as two colorless solutions are mixed together. Presence of bubbles means that there is a gas formed in the products side and that the one of the reactants can be an acid.
Answer:
V₂ = 70.80 L
Explanation:
Given data:
Initial volume of He = 45 L
Initial temperature = 250 °C
Final temperature = 550 °C
Final volume = ?
Solution:
Initial temperature = 250 °C (250+273.15 K= 523.15 K)
Final temperature = 550 °C (550 + 273.15 k= 823.15 K)
According to Charles Law.,
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 45 L × 823.15 K / 523.15 K
V₂ = 37041.75 L.K / 523.15 K
V₂ = 70.80 L
Answer:
A unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of an atom of carbon-12. It is equal to approximately 1.66 x 10-27 kg.
Explanation:
- According to Pascal’s principle, for a certain fluid in a totally enclosed system, a change in pressure at a given point in the fluid is transferred to all points in the fluid, as well as to the enclosing walls.
- This is illustrated by the fact that the pressure inside an enclosed system is the same according to the relation [ pressure = force/area ]. Therefore, the change in pressure resulting from squeezing a ketchup bottle will be transferred equally to all parts of that bottle as well as its internal content.
- That’s how hydraulic machines, such as garbage trucks and hydraulic lifts function..
