What phase change is the following substance undergoing?

Chemistry
1 answer:
Dvinal [7]3 years ago
5 0

Answer:

b melting

Explanation:

The phase change the substance is undergoing is from solid to liquid and this is called melting.

  • To understand this process, we need to know the the substance changing.
  • A substance that contains particles that are not easily compressed and packed is a solid.
  • Solids have fixed shapes and volumes.
  • Liquids can easily flow although they cannot also be easily compressed.

The phase change from solid to liquid is facilitated by a melting process.

Scientists define work as the spending of energy.<br><br> True<br> False
Hoochie [10]
True; scientist define work as the spending of energy. This is because energy is required to move an object. For work to be done an object has to be moved from one point to another. Work is measured in joules similar to energy which is also measured in joules. Mathematically, work done is given by the product of force and distance moved by an object or a body.

What is the difference between a amalgam and alloy.
Gennadij [26K]
Combinations of different metals form alloys. An alloy composed by mercury and other metal (or metals) forms amalgam. When a true alloy is formed, the component metals are mixed together at a temperature which is greater than the melting point of all of them.Apr 7, 2017

Mass has to do with how many particles
Ganezh [65]

The law of definite proportions agrees with Dalton atomic theory.

What is Dalton atomic theory?

It state that all matters is made of very tiny particles called atom. atoms are individual particles which can not be created or be destroyed in a chemical reactions. Atoms of given elements are identical in mass and chemical properties. Atoms of

different elements have different masses and chemical properties.

The law of definite proportions also known as proust's law ,state that a chemical compound contain the same proportion of elements by mass.this law is one of the stoichiometry .

Thus ,

This is the reason why it is agrees with dalton atomic theory.

How can equilibrium of a closed system chemical reaction be disturbed? Select all that apply.
charle [14.2K]

The correct answers are :

Changing the volume of the system.

Changing the temperature of the system.

Equilibrium will remain unaffected if the concentration of products and reactants are kept the same, and the temperature of the system is kept constant.

As the system is closed, we cannot add or remove products or reactants.

Change in temperature will shift the chemical equilibrium towards the reactant or product depending on whether the reaction is exothermic or endothermic.

Also change in volume  will shift the chemical equilibrium of a chemical reaction if the reactants or products or both are gases.
