Does sugar dissolve faster in hot or cold water? Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, […]
How do you ensure accuracy in a titration?
How do you ensure accuracy in a titration? Terms in this set (9) Meniscus at eye level. To avoid parallax error. White tile. To see end point clearer. Remove funnel before titrating. Increases the vol making the titre smaller. Dropwise addition. No bubbles in pipette & burette at the tip. Swirling during titration. Few drops […]
What is the evidence that volcanic activity can affect global temperatures?
What is the evidence that volcanic activity can affect global temperatures? The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics […]
What can be used to identify a material?
What can be used to identify a material? To identify a substance, you would compare the density of an unknown substance with the densities of known substances. Examples: The densities of wood, plastic and steel are all different. What are the steps to identify a substance? Four steps to successful substance identification Analyse your substance. […]
Why jet streams have such a high velocity?
Why jet streams have such a high velocity? Temperature also influences the velocity of the jet stream. The greater the difference in air temperature, the faster the jet stream, which can reach speeds of up to 250 mph (402 kph) or greater, but average about 110 mph (177 kph). Can the jet stream reverse? Now, […]
What keeps the heat in Earth?
What keeps the heat in Earth? There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive […]

For example, the volume of a bowl is the amount of space inside the bowl or how much water, for example it would take to fill the […]
What are the 2 hallmarks of science?
What are the 2 hallmarks of science? Top 9 Main Characteristics of Science – Explained! Objectivity: Scientific knowledge is objective. Verifiability: Science rests upon sense data, i.e., data gathered through our senses—eye, ear, nose, tongue and touch. Ethical Neutrality: Science is ethically neutral. Systematic Exploration: Reliability: Precision: Accuracy: Abstractness: What are the four goals of […]
How can models help scientists?
How can models help scientists? Models use familiar objects to represent unfamiliar things. Models can help you visualize, or picture in your mind, something that is difficult to see or understand. Models can help scientists communicate their ideas, understand processes, and make predictions. What are some models used in science? Physical models, mathematical models, and […]
