density
Yes, a solid would have the same mass on the moon as it would on earth. An object's mass is independent of the force of gravity, so its mass would remain the same even in the absence of gravity (e.g. on a spaceship). What would change is the weight, which is measured with mass in proportion to gravity.
Nobody. It is impossible to walk on Neptune as there is no solid surface. The only object where people have walked other than Earth is the moon.
What is a solid center of eath
solid rock
Earth has a solid metal inner core and a liquid metal outer core. Most of the rest made up of rocks in a molten state, but with a solid "crust". Finally there is a gas atmosphere.For simplicity scientists call Earth a solid planet to distinguish it from the gas planets, like Jupiter.
How does particle behavior change as an object changes from a solid to liquid to gas
Adding heat to the object if the object is a solid.
The earth is a 3-dimensional (solid) object.
A change of state is a change in the object from a solid to a liquid. Other changes of state are a solid to a gas or from a liquid to a solid.
Snowflakes.
you freeze the object.
Earth is the largest fully rock object we know of. Neutron stars are the largest solid-like object we know of, but they aren't really fully solid. Somewhere between solid and liquid.
Geology is the study of solid Earth, its rocks and the processes by which they change.
A solid object like an ice cube can be liquid. How you ask? you can just heat it up! to change a liquid object back to a solid, you just freeze it!
a phase change from solid to gas
The property of the object would change "solid, liquid, or gas"
Solid
