Answer:
6.286 L.
Explanation:
Applying Charles Law,
V/T = V'/T'............................... Equation 1
Where V = Initial volume of the balloon, T = Initial Temperature of the balloon, V' = Final volume of the balloon, T' = Final Temperature of the balloon
make V' the subject of the equation
V' = VT'/T............................ Equation 2
Given: V = 6.50 L, T = 31 °C = (273+31) K = 304 K, T' = 21 °C = (273+21) K = 294 K
Substitute into equation 2
V' = 6.5(294)/304
V' = 6.286 L.
Hence the new volume in the balloon = 6.286 L.
Answer: When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. ... That greater density of molecules increases the number of collisions. When you decrease the pressure, molecules don't hit each other.
Explanation: i hoped that helped!!!!!!!
The metal which will reach the highest temperature is the metal with the lowest specific heat capacity.
<h3>What is the amount of heat added to each metal?</h3>
The amount of heat Q = mcΔT where
- m = mass of metal
- c = specific heat capacity of mateal and
- ΔT = temperature change
<h3>Temperature change of the metal</h3>
Making ΔT subject of the formula, we have
ΔT = Q/mc
Given that Q and m are the same for each metal,
ΔT ∝ 1/c
We see that the temperature change is inversely proportional to the specific heat capacity.
Since the metals are at the same temperature, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.
So, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.
