Answer:
Húsavík, Iceland, with its volcanic landscape,
Answer:
a) 
, b) 
Explanation:
a) According to the First Law of Thermodinamics, the system is not reporting any work, mass or heat interactions. Besides, let consider that such box is rigid and, therefore, heat contained inside is the consequence of internal energy.
The internal energy for a monoatomic ideal gas is:
Let assume that cubical box contains just one kilomole of monoatomic gas. Then, the temperature is determined from the Equation of State for Ideal Gases:
The thermal energy contained by the gas is:
b) The physical model for the cat is constructed from Work-Energy Theorem:
The speed of the cat is obtained by isolating the respective variable and the replacement of every known variable by numerical values:
Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets. The general structures of the jovian planets are opposite those of the terrestrial planets. Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers of gas. Made almost entirely of hydrogen and helium, these planets do not have solid surfaces.
Answer:
gravitational force and outward pressure
Explanation:
The stars are very massive stellar objects, so they have a strong gravitational force, which drives the star to contract itself, but also in stars there are nuclear reactions such as fusion of hydrogen and other elements, that releases energy and creates a pressure from the center to the star exterior, an outward pressure that goes against the gravitational force. So when a star is stable these two forces exist in equilibrium or in balance, in which the star does not collapse by gravity or disintegrate by its outward pressure.
The appliances with thermostat are designed in such a way that it will provide heat waste energy by converting electrical energy to thermal energy. ... It converts thermal energy into mechanical energy. The nightlight that is used, converts electrical energy to visible light, which is a form of radiant energy.
