Answer:

you melt it

Explanation:

You change a solid to a liquid by melting it.

for example ice becomes a liquid by melting.

Answer:

Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid.

Explanation:

Answer:

0.5 g/ml

Explanation:

becace the density of an object is its mass divided by its volume

0,5 g / ml

Explicação:

porque a densidade de um objeto é a sua massa dividida pelo seu volume

Answer:

Tendrils can be formed from modified leaves, leaf tips, leaflets, or stipules. ... There is always a scale leaf at the point where the tendril branches. There are 4 types of Stem tendrils – Axillary (Passiflora), Extra-axillary (Cucurbita), Apical bud tendrils (Grapevine), and Inflorescence tendrils (Cardiospermum).

Answer:

Explanation:

One of the properties of a liquid is that, it's particles move freely (not tightly packed) hence the reason for it's free flowing (no definite shape) when shaken in a container, unlike a solid whose particles are tightly packed with restricted/no movement and hence the reason for it's compactness and it's definite shape.

When a plastic solid (whose particle is tightly packed and have a restricted movement/no movement) is placed near a heat source, it's particles gains energy in the process and starts to move (though slightly free) and become less tightly packed hence the reason it is observed that plastic solids near a heat source melts.

From the above, it can be deduced that a liquid and a plastic solid near a heat source have there particles move freely (and not tightly packed) hence making the two substances flow freely with no definite shape.

transition metals are good conductors of heat and electricity and it can hammered  into shape easily and have high melting points.

Transition metal are the chemical elements which have valence electron and it can participate in chemical bonds formation process in two shells.

The position of the transition metals in periodic table is the middle portions of the long periods between the groups on the left-hand side and the groups on the right.

Most of the transition metals  are hard, strong, and lustrous and it has high melting and boiling points, good conductors of heat and electricity.

Some of the elements are important technologically are titanium, iron, nickel, and copper as they are used in electrical technology.

Other transition metals are used in useful alloys, with one another and with other metallic elements, dissolve in mineral acids, platinum, silver, and gold are some Nobel transition metal.

You can test whether a substance is soluble by heating the substance up.

Solubility is the property that a substance has to be able to dissolve in another that can be called a solvent. Whether a substance is polar or nonpolar depends a lot on the solubility of the substance since with this the substance is more or less soluble. The more polar a substance is because of its functional groups, the more soluble it will be.

Solubility is determined by the intermolecular forces that exist between the solvent and the solute and not all substances will be able to dissolve in others, such as oil cannot dissolve in water

A good way to know if the solute dissolves is by heating the solution, so the substance that dissolves is the solute and the one that remains will be the solvent.

Therefore, we can confirm that you can test whether a substance is soluble by heating the substance up.
