Answer:
1. Thermal Energy is the internal energy that is produced from the temperature of a heated substance/object.
2. From the potato to the soup and from the soup to the surrounding room
Explanation:
1. When an object or substance is heated it causes a rise in temperature which makes the atoms and molecules within the object move/vibrate faster and collide with each other. This kinetic energy energy comes from the temperature of the object being heated and is the thermal energy.
2. The atoms present in a hot object have higher kinetic energy when compared to a colder object and usually flow towards the colder object. This is why it is possible for the hot potato whose temperature is higher than the bowl of soup to flow towards the soup and from the soup to the surrounding room.

The meridian directly opposite the Prime one ... roughly down the middle of the Pacific Ocean ... is the meridian of <em>180° longitude, both East and West.</em>
Technically, it should also be the International Date Line, but it's not. The International Date Line has been defined with several kinked segments in it, in order to avoid having it cut through the few islands that lie along 180°.
If it were allowed to do that, there would be nations that would have two different calendar dates on the same island. Kids who live on one side and go to school on the other side would constantly be either cutting school or showing up on Saturday, and people would be missing their dental appointments on the other side. Much easier just to put a kink in the International Date Line so that whole country is on the same calendar date.
Answer:
15.848 kJ
Explanation:
A gas is confined in a 0.47 m diameter cylinder by a piston, on which rests a weight. The mass of the piston and weight together is 150 kg. The local acceleration of gravity is 9.813m⋅s−2,and atmospheric pressure is 101.57 kPa
Solution:
Given that the diameter (d) = 0.47 m, the mass of piston and weight (m) = 150 kg, the acceleration due to gravity (g) = 9.813 m/s² and the atmospheric pressure () = 101.57 kPa = 101.57 * 10³ Pa
The area (A) = πd²/4 = π * 0.47² / 4 = 0.1735 m²
The force due to atmosphere (Fa) = * A = 101.57 * 10³ * 0.1735
Fa = 17622 N
Force due to piston and mass () = m * g = 150 * 9.813 = 1471.95 N
The total force exerted (F) = + Fa
F = + Fa
F = 17622 N + 1471.95 N
F = 19093.95 N
The work done by the gas (W) = total force * change in distance
W = F * Δx
W = 19093.95 N * 0.83 m
W = 15848 J
W = 15.848 kJ
