<span>Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. The heat capacity of aluminum at 25 degrees celsius is 0.9 J/g-C. It is expressed as follows:</span><span>

Heat = mC(T2-T1)
5800 J = 152000(0.90)(</span>ΔT)

ΔT = 0.42 °C change in temperature

Answer: 2.98 K

Explanation:

Q= m\times c\times \Delta T

Q= heat gained  or released= 5800 J

m= mass of the substance = 15.2 kg = 15200 g   (1kg=1000g)

c = heat capacity of  lead= 0.128 J/gK      

\Delta T={\text{Change in temperature}}=?  

5800J=15200g\times 0.128J/gK\times \Delta T

\Delta T= 2.98K

Thus change in temperature is 2.98 K.

Levart [38]

Answer:

Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.

Explanation:

When a gas is paced in a container, the molecules of the gas have little or no intermolecular interaction between them. There is a lot of space between the molecules of the gas.

The gas molecules move at very high speed and collide with each other and with the walls of container.

The collision of these particles with each other is perfectly elastic hence the kinetic energy of the colliding gas particles do not change.

C. Magma from venus mantle erupted as lava.

Explanation:

A volcano is a land form which results from the eruption of molten rocks (lava) on the surface. Volcanic rocks are a special type of igneous rock that forms when molten rock cools and solidifies on the surface.

For a planet like Venus which is presently not active and little to no movement occurs within the plates, the volcanisim must have occurred when the planet was relatively young and it must have been millions of years ago.

It is widely believed that Venus was geologically active in times past. Mantle generated lava must have solidified on the surface in times past to have formed the volcano.

Evaluating other options:

Impact of space objects on Venus would lead to the formation of a crater which is a depression on the surface. The rock would be mostly metamorphic.

If water was ever present in Venus, they would have produced sedimentary rocks instead. The erosive power of water is not high enough to cut through the crust. Also, water would not aid the formation of volcanoes.

Heat is not enough to from volcanoes. Other factors are also in play.
