Mr. Shepherd has gone outside to shovel snow on a cold day. How does his body maintain a relatively constant body temperature? What is this process called?
A.1 It is cold outside and you watch snow falling into a pot of liquid water, you estimate it has about a pint of water (0.5kg). When you start watching when the water in the pot is at 0°C and completely liquid. At certain point the water begins to freeze. How much ice (total) is in the glass at the moment it freezes completely? Draw the three-phase diagram and the energy interaction diagram for this process, mark initial and final...
When does an object that is thrown into the air reach its maximum potential energy? When does an object that is thrown into the air reach its maximum kinetic energy?
where does hot rising air get its heat from? Why does air get colder as it ascends, if it is getting closer to the sun? If this is because air is moving away from the earth (a possible source of heat) why is it that snow can be on the ground when ambient temperature is above freezing point? Water is a better conductor of heat than air is
How can global warming be real when there is so much snow and cold weather? That’s what some people wondered after a couple of massive snowstorms buried Washington, DC, in the winter of 2009–2010. Politicians across the capital made jokes and built igloos as they disputed the existence of climate change. Some concluded the planet simply could not be warming with all the snow on the ground.These comments frustrated Joseph Romm, a physicist and climate expert with the Center for...
why does a pool at 72 degrees F feel cold, but air at the same temperature feel warm?
Why does the water in the earthenware container stop boiling as soon as the pot is removed from the fire, and in the metal vessel it boils for a while?
When you leave a cold bottle of soda out on a warm humid day, water begins to condense on the surface of the bottle. Describe what is happening in terms of energy change
Why does water have a higher boiling point than ethanol? How does this property allow distillation to work? 1 paragraph please
Thumbs up for good answer. Why does the liquid in the round
bottom flask turn light pink?, please explain (This happened
during/after step 2). This is the procedure and the experiment is
called Synthesis of Artificial Flavorings by Fischer
Esterification.
Thank you!
