It’s a bit hard to see the images on the first row but I can answer the second half for you.
The order is B, C, A for highest thermal energy to lowest thermal energy. The highest thermal energy has the most space between particles and the lowest thermal energy has more spaces between particles.

Suppose a helium-3 nuclide transforms into a helium-4 nuclide by absorbing a proton and emitting a positron. Complete the nuclea
saw5 [17]

<u>Answer:</u> The nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.

<u>Explanation:</u>

Nuclear reaction are defined as the reactions in which nucleus of an atom is involved.

Positron emission is defined as the emission process in which positron particle is emitted. In this process, a proton gets converted to neutron and an electron neutrino particle.

_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e

The chemical equation for the reaction of He-3 with a proton follows:

_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0e

Hence, the nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.

What is the mass of 4.2kg gold when it's transferred to a planet having twice the gravity of earth
rjkz [21]

Answer:

The only relationship is that the larger the mass of an object the more gravitational force it has. So... something that has more mass has more gravity. The mass of 4.2kg of gold when transferred to this new planet is still 4.2kg. However, the WEIGHT (not mass) is now doubled to 8.4kg. Mass is constant it is how much matter something is made up of. Weight depends on the gravitational force. Moreover, I would look at other answers too (I'm not entirely confident of saying that the weight is 8.4kg since I don't have any gravitational equations in front of me it just sounds logical).

According to the data, how much energy would be liberated burning 0.554 kg of olive oil?
nirvana33 [79]

Answer:

2.18×10⁴ kJ are liberated when you burn 0.554 kg of olive oil

Explanation:

The chart indicates that ΔH combustion for the olive oil is 39.31 kJ/g which means that, when you burn 1 g of olive oil, you have 39.31 kJ of heat.

In this case, the mass of olive is 0.554 kg. Let's convert the mass from kg to g → 0.554 kg .  1000 g / 1kg = 554 g

Now, the conversion factor:

554 g . 39.31 kJ / 1g = 2.18×10⁴ kJ
