Why does the liquid in the thermometer go up and down when the weather changes?
The liquid in the thermometer expands or contracts based on temperature changes. When the weather is warmer, the liquid expands and rises up the tube, and when it's cooler, the liquid contracts and goes down. This movement indicates the temperature changes on the thermometer scale.
If an ice cube is placed in a pot that is heated what will happen after it has melted is it a chemical or physical change?
When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.
What happens when objects are placed into liquid hydrogen?
When objects are placed into liquid hydrogen, they become extremely cold due to the low temperature of liquid hydrogen (-252.87°C). Depending on the material, they may become brittle and susceptible to breaking. Some materials may also experience changes in electrical conductivity or magnetic properties when exposed to such extreme cold.
What does ice cube bang?
When an ice cube is placed in a warm drink, it absorbs heat energy from the liquid causing it to melt. This release of energy can create popping or cracking sounds as the ice changes state from solid to liquid.
What happens if density of a solid substance is more than liquid it is placed?
If the density of a solid substance is greater than that of the liquid it is placed in, the solid substance will sink to the bottom of the liquid. This occurs because objects with higher density will displace an equal volume of the lower density liquid, causing the solid to sink.
What changes shape when placed in different container?
Any Liquid or Gas
What change takes place in the liquid inside a thermometer when it is placed into somthing cold?
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
How does a solid dissolve into a liquid?
a solid dissolves into a liquid because of the free inter molecular spaces in between the molecules of the liquid or the solvent......... for example if we dissolve sugar in water and stirr the water , the sugar dissapears . this happens because the molecules of water are not yery closely placed and the sugarparticles go and fit inside the molecular spaces.......

What changes shape but doesn't change volume?
A gas can change shape but it doesn't change volume, a liquid also changes shape but doesn't change volume.

How are the three primary states of matter identified in a chemical equation?
By single lower-case letters within parentheses placed after a molecular or atomic formula: (s) for solid, (l) for liquid, and (g) for gas.

What state of matter changes shape when placed into a container?
A gas changes shape when placed into a container. Gases do not have a fixed shape or volume, and they expand to fill the space available to them. This is in contrast to solids and liquids, which have a fixed shape and volume.

Why does liquid rise higher when an object placed in it?
The liquid rises higher when a object is placed inside of it is because the mass of the object takes up space inside the liquid, which pushes the liquid in a direction that has space available.
What object placed in a liquid of greater density will do this?
an object will float on a denser liquid
