Youre planning to study in Europe, and you want a transformer designed to step 230-V European power down to 120 V needed to operate your stereo. (a) If the transformers primary has 460 turns, how many should the secondary have? (b) You can save money with a transformer whose maximum primary current is 1.5 A. If your stereo draws a maximum of 3.3 A, will this transformer work?
BIOL 300 Foundations of Biology – Telleen Section 3 pt 4 1. Heat storage – temperature is a measure of how rapidly individual molecules are moving. Due to H-bonds, H2O requires lots of energy to disrupt its organization. Thus, it takes lots of energy to heat, heats slowly, and holds temperature longer than most other molecules. This is why we can maintain a relatively stable body temperature 2. Ice formation – at low temperatures H-bonds don’t break easily resulting in a crystal structure. Interestingly, solid water (ice) is actually less dense than liquid water (this is why a beer can will explode if you put it in the freezer for too long!) 3. High heat of vaporization – Since an increase in temperature is
