I think the correct answer from the list of choices above is option B. <span>The chemical combination of two or more different atoms in fixed amounts is called a compound. There are two type of compounds namely the ionic and covalent compounds.</span>
The question is too broad. Depends of the battery and depends where do you connect it to.
define first a battery reaction and where it is connected to define if the reaction is endo or exothermic.
If a battery reaction is exothermic when it is connected to a circuit may be endothermic when it is charged (reverse reaction).
some batteries at low temperature tends to work less, that suggest, they may need absorb some energy from the surroundings.
Answer :
(a) The dimensions in are,
(b) The distance in centimeters is, 40.64 cm
Explanation :
(a) The conversion used :
and,
As we are given the thickness, width, length dimensions in inches, inches and feet respectively.
Now we have to determine the thickness, width, length dimensions in centimeter, centimeter and meter respectively.
The dimensions in are,
(b) The conversion used :
As we are given the distance in inches. Now we have to determine the distance in centimeter.
The distance in centimeters is, 40.64 cm
Answer is: <span>the new pressure on the gas is 0.25 atm or 25.33 kPa.
</span>Boyle's Law: the
pressure volume law - <span>volume of a
given amount of gas held varies inversely with the applied pressure when
the temperature and mass are constant.
p</span>₁V₁ = p₂V₂.<span>
1 atm · 5.00 L = p</span>₂<span> · 20.0 L</span>.<span>
p</span>₂ = 1 atm · 5 L ÷ 20.0 L.<span>
</span>p₂ =
0.25 atm, but same amount of helium.
<span>Bodies of magma rise in the crust until they reach a point of neutral buoyancy. The expansion of gases brings the magma closer to the surface and drives eruptions. When more gases are dissolve into the magma, there would more chances of explosion. Hope this answers the question.</span>
