What is added to change a solid to a liquid?
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
What is necessary to make any matter change phases?
Cooling or Heating First of all we have 3 phases, Gas, Liquid and Solid to change from gas to liquid to solid, cooling is required and to change from solid to liquid to gas, heating is required This type of heat is called latent heat, always think of water as an example Ice --> Water , heating Water--> Water Vapour, more heating
What is added to ice to make it change from a solid to a liquid?
heat
What h is needed to make the water evaportate and leave the salt behind?
Heat is needed to make the water evaporate from a salt solution. When heat is applied, the water molecules absorb energy, break their bonds, and change from a liquid to a gas, leaving the salt behind.
What does matter change into if heat is added?
Heat makes most things expand. Or in other words, heat makes matters less dense.(With the very known and remarkable exception of water, ice which will decrease in size when it becomes water and becomes more dense until it reaches 4 degrees Celsius, from which point on it will expand again.)Heat can make matters change state.Ice (solid) into water (liquid), water (liquid) into steam (gas).
How do you change solid water to liquid and liquid water to gas?
You can change both of these by increasing or decreasing the speed of the molecules (kinetic energy), or by increasing or decreasing the heat applied (thermal energy). If you want to melt ice, you can increase the kinetic energy by increasing the thermal energy. The opposite occurs if you want to freeze water.
What kind of state change did some of the water go through to make it disappear?
The water went through a phase change from liquid to gas, in a process known as evaporation. The heat energy from the surroundings caused the water molecules to gain enough kinetic energy to escape into the air as water vapor.
When liquid water freezes is it releasing or absorbing heat from the surroundings?
When liquid water freezes, it releases heat to the surroundings. This is because as water cools and freezes, it is converting its energy to a lower state, thereby releasing energy in the form of heat to the surrounding environment.
When a liquid becomes a solid where does the heat energy in the liquid go?
A gas has more heat energy, often called thermal energy, than a liquid, even if both the liquid and gas are at the same temperature. Consider that the gas molecules have more thermal energy than liquid molecules of that same substance. The gas molecules are "free" to move around more because they have more kinetic energy than molecules of the liquid. And kinetic energy is function of thermal energy. If we consider the case of water molecules to illustrate our point, when a pan of water is boiling, the water molecules escaping the pan as a gas have more kinetic energy than the ones making up the liquid water that is still in the pan. Also consider the case of water that is evaporating. Wet your finger and blow on it. The liquid water on your finger cools as the evaporating water molecules take thermal energy from that liquid to make their change of state possible. It takes an increase of thermal (heat) energy to change a liquid into a gas.
Melting of ice is a physical change?
Yes because the ice melts into water. Then, it can be reversed. You can freeze the water and make ice. I believe you can also crank up the heat and turn the water into water vapor and then turn it down turning the gas into a liquid which you can freeze. So yes. It's a physical change.
What type of change occurs when liquid is cooled to make ice cubes?
A physical change occurs when liquid is cooled to make ice cubes. This change involves the substance transitioning from a liquid state (water) to a solid state (ice) without any change in its chemical composition.
Is boiling water to make steam a physical change?
Yes, boiling water to make steam is a physical change. This is because the water undergoes a change in state from liquid to gas without any change in its chemical composition.
