Is heat added or removed in condensation? A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs. Heat is released when a vapour condenses. What happens when a solid is heated Class 9? […]

What is importance of nucleus?
What is importance of nucleus? The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm. What is Nucleus explain? […]
Which is an empirical formula?
Which is an empirical formula? An Empirical formula is the chemical formula of a compound that gives the proportions (ratios) of the elements present in the compound but not the actual numbers or arrangement of atoms. This would be the lowest whole number ratio of the elements in the compound. What is the empirical formula […]
What materials can a scrap heap magnet move?
What materials can a scrap heap magnet move? The only magnetic elements are iron, cobalt and nickel. this means that electromagnets can only attract these metals although they can also attract steel this is because steel is mainly made of iron. Are gas showers cheaper than electric? Given the cost of gas is only about […]
What is the difference between batteries in series and batteries in parallel?
What is the difference between batteries in series and batteries in parallel? In a series connection, batteries of like voltage and amp-hour capacity are connected to increase the voltage of the overall assembly. In a parallel connection, batteries of like voltages and capacities are connected to increase the capacity of the overall assembly. Why are […]
What causes groundwater to rise?
What causes groundwater to rise? When recharge occurs in an unconfined aquifer, the water table rises to a higher elevation, much like water level in a bucket will rise as water is added to it. One inch of precipitation moving underground to the water table will cause the groundwater level to rise considerably more than […]
What is the purpose of theory in research?
What is the purpose of theory in research? Theories are formulated to explain, predict, and understand phenomena and, in many cases, to challenge and extend existing knowledge within the limits of critical bounding assumptions. The theoretical framework is the structure that can hold or support a theory of a research study. Why do we need […]
Where are lipids found in food?
Where are lipids found in food? Introduction. In foods, lipids are mainly found in the form of triacylglycerols (triacylglycerides) (TAG), which make up to 99% of lipids of plant and animal origin (Fennema, 1996). Phospholipids (PL) are important structural lipids in foods and cell membranes. Where are lipids and oils found in a plant? Essential […]
