Divide the object’s weight by the acceleration of gravity to find the mass. You’ll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you’re measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.

Generally speaking, the cups for measuring liquids are clear and have a handle that begins near the top and travels down almost to the cup’s bottom. Cups for measuring solids are usually opaque plastic or metal and the handle is fastened to the top of the measuring cup and is perpendicular to the cup.

The most widely used method for determining density of solids and liquids is the gravimetric buoyancy technique which utilizes Archimedes’ principle. Archimedes’ principle states that a body immersed in fluid experiences a buoyant force acting upwards on it.

Hydrometer, device for measuring some characteristics of a liquid, such as its density (weight per unit volume) or specific gravity (weight per unit volume compared with water).

Divide the object’s mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.

The density of a liquid is a measure of how heavy it is for the amount measured. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is more dense. If a liquid that is less dense than water is gently added to the surface of the water, it will float on the water.

Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container. To find the volume of the fluid, you simply measure it very carefully in a graduated cylinder.

Once you know specific gravity, you also know density, because you just multiply specific gravity by the density of water, which is 1 gm/cm3, to get density. You can then find the mass of a specific volume of the liquid by multiplying its density by the volume of the liquid you have.

Liquids do not have definite shape, but they do have definite mass and volume. Liquids are similar to solids because their atoms are close together, but what makes a liquid different is that those atoms can move around.

An apple is one example of a solid.

A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. (a) Solid O2 has a fixed volume and shape, and the molecules are packed tightly together.

Capillary action is the ability of a liquid to flow through narrow spaces without the … Water, ethanol, household bleach, blood, paint, milk, gasoline, mineral oil, acetone and butyl alcohol are examples of liquids.

Examples of Liquid to Solid Phase Transition (Freezing)

• Water to ice – Water becomes cold enough that it turns into ice.
• Liquid to crystals – Most liquids freeze by a process that is known as “crystallization,” whereby the liquid forms into what is known in the scientific world as a “crystalline solid.”

The process of a solid becoming a liquid is called melting. It requires energy for a solid to melt into a liquid. Every pure substance has a certain amount of energy it needs to change from a solid to a liquid. This amount is called the enthalpy of fusion (or heat of fusion) of the substance, represented as ΔH fus.

To convert a solid into a liquid you need to heat the solid beyond its melting point. The atoms absorb this heat and vibrate more and more. Hence, the atoms of solid move apart and ultimately it starts to flow.

Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up. The changes only happen when the substance reaches a particular temperature.

When you reach your boiling point, the molecules in your system have enough energy to become a gas. When the temperature drops, energy will be transferred out of your gas atoms into the colder environment. When you reach the temperature of the condensation point, you become a liquid.

Boiling and Condensation Again, at a certain temperature called the boiling point, the molecules will gain enough energy to break free and become a gas. The boiling point for water is 100 degrees C (212 degrees F). When the opposite occurs and a gas becomes a liquid, it is called condensation.

Liquefied gases are gases which can become liquids at normal temperatures when they are inside cylinders under pressure. As gas is removed from the cylinder, enough liquid evaporates to replace it, keeping the pressure in the cylinder constant.

If energy is continually removed from a liquid, then the liquid freezes to become a solid.

If a gas is cooled, its particles will eventually stop moving about so fast and form a liquid. This is called condensation and occurs at the same temperature as boiling. Hence, the boiling point and condensation point of a substance are the same temperature.

Matter can exist in three different states: solid, liquid or gas. In evaporation, matter changes from a liquid to a gas. Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.

The molecules move around very little and have a low amount of energy. Molecules in a liquid have more energy than molecules in a solid. And if you heat it up even more, the molecules will speed up so much that they won’t be stuck together at all.
