High-altitude mountain climbers do not eat snow, but always melt it first with a stove. to see why, calculate the energy absorbed from a climber's body under the following conditions. the specific heat of ice is 2100 j/kg⋅c∘, the latent heat of fusion is 333 kj/kg, the specific heat of water is 4186 j/kg⋅c∘.

What happens to atoms and chemical bonds during a reaction?

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.

In a system, when potential energy decreases, then entropy also decreases. true false
