Answer: Distillation
Explanation:
Distillation is the process of purifying a liquid by successive evaporation and condensation. Water vaporises at a lower temperature compared to the ink pigment, therefore, the mixture is heated to boiling so that the water evaporates leaving the ink pigments in the flask. The evaporated water can the be passed into a condenser which converts the water vapour into liquid.
Answer: Distillation
Explanation: Separate ink from water using a process called distillation. This is a process of separating two substances mixed together. Water vaporizes at a lower temperature than the ink pigment so if you heat them, the water evaporates, leaving the ink pigment in the flask.
Answer:
Explanation: The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables.
Answer:
physical
Explanation:
no chemical reaction is occurring
anyone know?
Explanation:
When we move across a period then there occurs an increase in the number of electrons of atoms from left to right. These electrons are added to the same sub-shell.
For example, elements present in row 2 will have electrons present in n = 2 which is the highest energy level for row 2 elements.
Hence, there are different number of valence electrons present in the elements of a row.
Whereas when we move down a group then elements have same number of valence electrons. As a result, they tend to show similar chemical properties.
But since, there are no same number of valence electrons in the elements of a row. Hence, they do not show similar chemical properties. Therefore, elements of a row do not behave same in chemical reactions.
Thus, we can conclude that we disagree with the hypothesis given by the student.
it really easy its true
B.a definite shape,but no definite volume
C.No definite shape,but a definite volume
D.no definite shape and no definite volume
A substance in the solid phase (state) of matter has a definite shape and a definite volume.
Volume is the amount of space taken up by an object, while capacity is the measure of an object's ability to hold a substance, like a solid, a liquid or a gas. Volume is measured in cubic units, while capacity can be measured in almost every other unit, including litres, gallons, pounds, etc.
Matter in the solid-state maintains a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place.
Hence, option A is correct.
