What substance has a density less than 1 gmL?
For example ice and lithium.
Is it true a physical change never alters the form or appearance of a substance?
No. For example, ice to water.
When does a substance changes from a solid to a liquid?
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
How can the temperature of substance remain the same even if the substance is absorbing thermal energy.?
For example, when ice is melting, the absorbed thermal energy is used to change the phase of the substance - a type of potential energy.
Is ice in a glass of water a substance or mixture?
if you are comparing the water and Ice then it is neither. they are both the same.From one point of view you have a mixture - even though they are the same - one is in the solid state and the other is in the fluid state.From another - its an homogeneous substance since they are the same element.To be literal as to your question: which is about the ICE itself and the water is not actually the substance in question. With that then the Ice is a substance and as long as it is ICE is is not mixing with the water. When the state changes from solid to liquid the melted liquid has become the other substance and is no longer ICE.
What cause a substance to change it state example ice to water?
Most commonly, either the addition or removal of heat
What happens after a substance goes through a chemical change?
Yes because when a chemical change happens the substance may not have some of the physical or chemical properties it had once before. An example of htis would be Dry Ice. This would be an example because dry ice was once just ice then they add a chemical and it turns into dry ice.
Is ice a mixture or a pure substance?
Ice is solid H2O so it is a pure substance, at least ideally.
When a substance from any state of matter to another is called a?
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
Is dry ice a substance?
Yes, dry ice is a substance. It is frozen carbon dioxide.
What tempereture make solid to liquid?
Depends on what substance. For example, Ice which is a solid, liquifies above 0 degrees Celsius
Is the melting point of a substance is the same as it's surroundings?
no this would depend on the atoms of the substance. for example if you have a block of ice and a block of butterthe block of ice would melt faster because its atoms move more faster to heat than butter does
