Laboratornye Po Fizike 8 Klass Korshak Savchenko Liashenko -

Alex’s year began with Thermal Phenomena . In the first lab, he carefully measured the cooling of water over time, plotting a graph that looked like a gentle slide. Later, he used a calorimeter to find the specific heat capacity of a metal cylinder. He dropped the hot metal into cool water, watching the thermometer climb as the two reached "thermal equilibrium"—the perfect balance of energy exchange.

Next came Electromagnetic Phenomena . Alex wound wire around an iron nail to create an electromagnet . He was amazed when a simple battery turned a piece of junk metal into a magnet strong enough to pick up paperclips. He then explored the magnetic field of a permanent magnet using iron filings, which mapped out invisible lines of force like a hidden fingerprint. laboratornye po fizike 8 klass korshak savchenko liashenko
