Answer:
V1 = 2221.33 L
Explanation:
The system is about a ideal gas. Then you can use the equation for ideal gases for a volume V1, temperature T1 and pressure P1:
(1)
And also for the situation in which the variables T, V and P has changed:
(1)
R: constant of ideal gases = 0.082 L.atm/mol.K
For both cases (1) and (2) the number of moles are the same. Next, you solve for n in (1) and (2):
Next, you equal these equations an solve for T2:
Finally you replace the values of P2, V2, T1 and T2:
Hence, the initial volume of the gas is 2221.33 L

Explanation:
The answer to Willem's experiment are as follows;
A) The two other measurements Willem will require to calculate the specific heat capacity of copper are;
- The mass of the copper block
- The change in temperature of the copper block after heat is supplied.
B) The block must be well insulated to ensure no heat energy is lost to the surrounding by conduction, convection and radiation and hence, all heat supplied is used to effect a change in temperature in the copper block as intended.
C) If the block is poorly insulated, energy is lost and hence, the result would be too high because more energy would be consumed in the process.

They are called magnetic poles.
Answer:
11×10⁵ J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 1000 kg
Height (h) = 110 m
Acceleration due to gravity (g) = 10 m/s²
Potential energy (PE) =?
The potential energy of the roller coaster can be obtained as follow:
PE = mgh
PE = 1000 × 10 × 110
PE = 11×10⁵ J
Therefore, potential energy of the roller coaster is 11×10⁵ J
