WebPhysical causes of climate change. Physical causes of global warming and cooling include:. Volcanic eruptions - large amounts of volcanic dust in the atmosphere shield the Earth from the sun, lowering the global temperature. For example, the eruption of Mount Pinatubo in 1991 caused a dip in global temperatures WebBy heating or cooling a substance, its state can be changed. There are four main changes of state : melting - the process of a solid turning into a liquid freezing - the process of a …

WebJan 5, 2016 · Heating and cooling curves are graphs of temperature over time for different substances, demonstrating the phase changes. See the curves for heating and cooling to identify the phase... WebCooling Curves Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.
