What happens to the air pressure inside a balloon when the balloon is squeezed to half its volume at a constant temperature? What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature? The atmospheric pressure decreases as they rise, so they expand. What causes pressure […]

Can you sue for IV infiltration? Most victims who have suffered a serious case of IV infiltration need to seek financial compensation through a claim or lawsuit to hold those negligent accountable for their actions. Skilled attorneys can build a strong case, proving negligence when the patient suffers serious medical complications. What does blowing a […]

Do cats run away if they are unhappy? Although in some cases cats running away is associated with anger, more often than not it is related to pure fear. Perhaps the cat just doesn’t trust you enough yet. When cats are scared, they often freeze up as an automatic reaction — causing them to bolt […]

What are the advantages of SI unit? (i) SI is coherent system of units, i.e., a system based on certain set of fundamental units. (ii) SI is rational system of units. i.e., it assigns only one unit to a particular physical quantity. (iii) SI is metric system, i.e., multiples and sub-multiples of the system can […]

What is an autocrine factor? The ability of cancer cells to produce and to respond to their own growth factors (autocrine secretion) has become a central concept linking oncogene and growth factor research. Antagonists of positive autocrine growth factors can inhibit growth of cancer cells in experimental animals. What is the purpose of autocrine signaling? […]

How do you write materials and methods? It is generally recommended that the materials and methods should be written in the past tense, either in active or passive voice. In this section, ethical approval, study dates, number of subjects, groups, evaluation criteria, exclusion criteria and statistical methods should be described sequentially. What are materials and […]

What Cooler keeps ice the longest? YETI Tundra 45 Does cooler color make a difference? Does Cooler Color Matter? Yes, cooler color does impact ice retention times, but not as much as many may be inclined to think. In the most extreme case, a white cooler held ice for half a day longer than a […]

What is a conclusion in the scientific method? A conclusion is a statement based on experimental measurements and observations. It includes a summary of the results, whether or not the hypothesis was supported, the significance of the study, and future research. What is an Experiment? It is a detailed procedure designed to test a hypothesis. […]

Is clear ice bad? Cloudiness indicates either trapped air or trapped impurities, or both. Sometimes these impurities will even contain unpleasant odors. This type of ice is therefore much healthier than cloudy ice to consume. It has fewer impurities, less air, and even fewer bacteria. Is clear ice safe to walk on? Ice is not […]

How does Lene Hau slow down a beam of light? Hau and her team have previously shown that a Bose-Einstein condensate — which they make here by cooling sodium atoms to about 600 billionths of a degree (colder than deep space) — can slow down a light beam and even bring it to a standstill. […]
