Jupiter is the largest planet in our solar system. It has a mass that is more than twice the combined mass of all the other planets. Its size is also significantly larger than any other planet, with a diameter of about 86,881 miles. Jupiter's large size is due to its composition, primarily made up of hydrogen and helium gasses. Its immense size and mass also contribute to its strong gravitational pull, making it a dominant force in the solar system.

Light propagates in a straight path when unobstructed by objects. This phenomenon, known as rectilinear propagation, is a fundamental principle of optics. When uninterrupted, light rays travel uniformly in a linear trajectory, demonstrating the inherent property of light to maintain a straight course in the absence of obstacles.

To turn solid ice into a liquid, heat needs to be added. Heat increases the temperature of the ice, causing the ice molecules to gain energy and move faster. As a result, the bonds holding the ice molecules together weaken, and the solid ice transforms into a liquid state.

Solids, liquids, gases, plasma, and Bose-Einstein condensates are the five known phases of matter. The primary distinction among these states lies in their structural properties rather than just the densities of the particles. Various factors, including particle arrangement and intermolecular forces, contribute to these differences.

Motion is the correct answer because it refers to the change of location or position of an object with respect to time. It is a fundamental concept in physics that describes the movement of objects in space. Motion can be described in terms of speed, velocity, and acceleration, and it plays a crucial role in understanding the behavior of objects and the laws of physics.

Mars is known as the red planet because of its reddish appearance. The planet's surface is covered in iron oxide, commonly known as rust, which gives it a reddish color. This distinctive feature sets Mars apart from other planets in our solar system.

Mercury is the closest planet to the sun. It is located at an average distance of about 36 million miles from the sun. Its proximity to the sun allows it to have the shortest orbital period of any planet in our solar system, completing one orbit in about 88 Earth days. This close proximity also means that Mercury experiences extreme temperatures, with surface temperatures reaching up to 800 degrees Fahrenheit during the day and dropping to -290 degrees Fahrenheit at night.
