Answer;

-During sublimation

Explanation;

-Carbon dioxide in its solid form is known as “dry ice,” because under common conditions it sublimates, turning directly into gas, rather than melting into liquid.

-The enthalpy of sublimation, or heat of sublimation, is the heat required to change one mole of a substance from solid state to gaseous state at a given combination of temperature and pressure,

-The low temperature and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water ice and leaves no residue as it changes state. Its enthalpy of sublimation is 571 kJ/kg

The answer for the given question above would be the third option. Carbon dioxide absorbs the most heat energy during SUBLIMATION. By definition, sublimation is the transition of a substance from the solid to the gas phase without passing through the intermediate liquid phase. Hope this answers your question.

A motor pushes a car with a force of 35 N for a distance of 350 m in 6 s.

labwork [276]

Answer:

2041.66666667

Explanation:

35 N → 350 METERS for 6 seconds

force distance

350 M / 6s = 58.3

58.3 x 35 N = 2041.66666667 work

Why does water in a bathtub overflow when you get in but it not in a lake

amm1812

Answer:

Explanation: In a bath tub you don't have that much space so when you get in your body makes it overflow by the weight that is on it. when you are in a lake you have all the space you want because it is bigger than a bath tub that is why.

According to Kepler's second law, Jupiter will be traveling most slowly around the Sun when at its aphelion.

Earth orbits in the shape of an ellipse around the Sun

The mathematical form of Kepler's third law measures the period in years and the distance in astronomical units (AU).

5. According to Kepler's second law, Pluto will be traveling fastest around the Sun when at __________.

According to Kepler's second law, Pluto will be traveling fastest around the Sun when at its perihelion.

6. The extent to which Mars' orbit differs from a perfect circle is called its _________.

The extent to which Mars' orbit differs from a perfect circle is called its eccentricity.

Explanation:

Earth is located at one of the Moon's orbit.

The mass of the Earth is greater than the mass of the Moon, therefore the moon will be attracted to the Earth for the gravitational force. Hence, it is the Moon the one that orbits the Earth and not the other way around.

Kepler's laws establish that:

All the planets revolve around the Sun in an ellipse orbit, with the Sun in one of the focus (Kepler's first law).

A planet describes equal areas in equal times (Kepler's second law).

The square of the period of a planet will be proportional to the cube of the semi-major axis of its orbit (Kepler's third law).

$T^{2} = a^{3}$

Where T is the period of revolution and a is the semi-major axis.

According to Kepler's second law, Jupiter will be traveling slower around the Sun when at its aphelion.

Since planets orbit around the Sun in an ellipse, with the Sun in one of the focus, in some moments of their orbit they will be closer to the Sun. It is known as perihelion when the planet is in the shorter distance to the Sun in its orbit, and aphelion when it is farther away from the Sun.

According with Kepler's second law to complete the same area in the same time, Jupiter slow down when it is at its aphelion. That is due to the force of gravity, since it is inversely proportional to the square of the distance:

$F = G\frac{m1m2}{r^{2}}$

Where G is the gravitational constant, m1 and m2 are the masses of the two objects and r is the distance between them.

So when the distance increases the force decreases, and the orbital speed slows down.

According to Kepler's second law, Pluto will be traveling fastest around the Sun when at its perihelion.

In the case of Pluto it will speed up when it is at its perihelion in accordance with Kepler's second law and since the gravitational pull will be greater because it is in a shorter distance from the Sun.

The mathematical form of Kepler's third law measures the period in years and the distance in astronomical units (AU).

One (1) Astronomical unit is defined as the distance between the Earth and the Sun (150000000 Km), where the distance is described by the semi-major axis in Kepler's third law.

The extent to which Mars' orbit differs from a perfect circle is called its eccentricity.

The eccentricity is the measurement of how pronounce a conic section is. An eccentricity equal to zero represents a circle.
