Which condition must exist in order for conduction?
This process of exchange of heat is known as conduction. For example, a metal spoon placed in a hot coffee mug shows flow of heat from coffee to the spoon. Thus, we can conclude that a condition which must exist in order for conduction to occur between two substances is that the objects must be touching each other.
Does temperature measure particle speed or kinetic energy?
Temperature is a measure of the average kinetic energy of the particles within a sample of matter.
What two conditions must exist for radiation to occur?
the presence of electromagnetic waves and direct contact of molecules. a temperature difference and the presence of electromagnetic waves.
What conclusion can ed make about the pots of water?
What conclusion can Ed make about the pots of water? The water in pot X has more kinetic energy than the water in pot Y.
Which needs less heat to increase its temperature water or sand?
Water has very high specific heat, which means that it needs to absorb quite a bit of energy before its temperature starts to change. Sand has a much lower specific heat, so it needs to absorb less energy.
Why does the sand at the beach get so much warmer than the water?
Sand heats up faster than water because sand has less specific heat than water. Hence sand has less specific heat than water it requires less amount of heat to increase it’s temperature which makes it heat faster comparatively.
Why is beach sand hotter than ocean water on a hot day?
In a hot day sand on a beach gets hotter than the water in the sea because sand gets hotter quickly than the water. a more appropriate answer would be that land(sand) has a higher specific heat point than water(sea) so it heats up faster than sea water during the day and vice versa.
What purpose would the heat lamps serve?
What purpose would the heat lamps serve? The heat lamps would serve the purpose of heating the land and water.
What purpose would the water serve?
A primary function of water is to serve as a lubricant. For example, it is found in saliva and is a substantial component in the fluid surrounding joints. Water is also in and surrounding body structures such as the brain, spinal cord and eyes.
What purpose does the sand serve?
Sand is a non-renewable resource over human timescales, and sand suitable for making concrete is in high demand. [2] Desert sand, although plentiful, is not suitable for concrete, and 50 billion tons of beach sand and fossil sand is needed each year for construction.
What is the difference between silica sand and regular sand?
In order to be considered a silica sand the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criteria, it will qualify as what’s often called ‘regular’ sand.
