! ! Project Title ! (DIY) In order to heat almost 10000 gallons of water using solar energy‚ we have designed and implemented a solar hea9ng device. The design concept is to use a black pipe to absorb heat from the sun light in order to heat the water flowing in the pipes. This solar

than the avg.KE of the particles in the bathtub‚ the thermal energy in the warm bath tub is higher because there are more particles in the tub than the cup. II. Heat Heat is the movement‚ or flow‚ of thermal energy. Heat always flows spontaneously from matter at a higher temperature to matter at a lower temperature. Heat and thermal energy are both measure in units of energy‚ the SI unit for energy is Joule(J). Another unit of energy that is commonly used is the Calorie. The food calorie

An easy way to understand this concept is through a simple demonstration. An insulator is a material that does not allow a transfer of electricity or energy. Materials that are poor thermal conductors can also be described as being

Question: Which heats and cools faster: sand or water? Hypothesis: The hypothesis is that sand will heat and cool more quickly than the same amount of water placed under the same conditions. This is because water has a higher specific heat capacity (4.18 J/g°C) compared to sand’s specific heat capacity (0.29 J/g°C). The specific heat capacity is how much heat energy it takes to change the temperature of the material one degree. Since water has a higher specific heat capacity it will take more heat energy

out if this project is even possible. Luna Abdallah et al created an experiment making it possible. To measure the amount of calories in a food‚ you first have to light it on fire. Your homemade calorimeter will trap the heat of the food and the water above it will trap the heat causing the water temperature to increase dramatically. You will then measure the change in temperature of the water from start to end. Calories are a measure of energy‚ so the energy gained by the water will be equal to

this lab‚ I calculated the heat of combustion of paraffin (candle wax) by burning a candle and holding a calorimeter (a soda can) filled with 98.7 mL of water above the flame. The heat released by the candle was absorbed by the water in the can. It was important to place the metal chimney around the candle so that minimal amounts of heat would escape; having too much heat lost to the atmosphere would cause extra error in the calculations. The assumption made was that all heat released from the candle
