Why do hot molecules move faster than cold molecules? Do the molecules in a liquid all have about the same speed or do they have a wide variety of speeds? Why do solids conduct better heat than liquids and gases? How is the speed of molecules of air...
Explain why water boils at a lower temp at higher altitudes than lower altitudes. What is thermal pollution? Explain. Explain how woolen clothes help us in winter against cold. If the polar ice caps of Earth were to melt, the oceans would be deeper, what effect would this have on E...
补充练习 Nearly everyone who plays or watches basketball believes in the hot hand. After making a couple of shots, players are thought to be more likely to h it their next few. But if a p layer misses several shots, people say he has gone cold and conclude he is less likely to make...
In particular, immersion plating is in principle a desirable process because it is faster, often easier to control, and less expensive process compared to electrodeposition, since many wafers can be processed in one batch and tooling is comparatively simple. However, immersion plating is self-...

" Water boils above [{MathJax fullWidth='false' 100^{\circ}C }] in a pressure cooker " state whether the sentence is true or false if it is true then why is food cooked faster in the pressure cooker? Which of the following processes is due primarily t...
Scientific methods: These methods include observation, synthesis, formulation, assumption and hypothesis, formation of theory, experiment, and conclusion of processes. It is a part of research methodology. Answer and Explanation:1 Research in a scientific way ...
the interplay between the buoyancy force and drag force causes large bubbles to move faster than small bubbles when subjected to the same pressure gradient d.) fluctuations in the background pressure can be synchronized with fluctuations in the pressure gradient, so that, even though the bubble is...
