The final temperature of the tea cup is 100°C.
<h3>What is internal energy?</h3>
The Internal energy is the energy of a substance due to to the constant random motion of its particles.
The symbol for internal energy of a substance is U and it is measured in Joules.
ΔU = q + W
- W is the mechanical work.
In conclusion, the final temperature of the tea cup at room temperature of 24 °C which is heated until it has twice the internal energy is 100°C.

<h2>C
omets are made of Chunks of rock, gas, Ice, and dust. The Answer is A and C.</h2>
Explanation:
Comets is one of the main types of space rocks. Recent researchers has termed Comets as 'dirty snowballs' of space, that contains ice, rock, gas and dust. The solid center of the comet is less than 10 kilometers across.
Comets are believed to have originated beyond Neptune and Pluto. It is called the Oort Cloud that surrounds the solar system.
It carries carbon dioxide, methane, ammonia, and many more gases. According to Astronomers, comets are assumed to be the leftovers of the material that was initially the part of solar system about billion years ago.
