Surface energy

Waves are disturbances that transfer energy from one place to another without transferring the particles of a medium. Some waves must travel through matter, known as the medium (mechanical waves). And when they travel through the medium they cause the particles to vibrate. Some types of mechanical waves are sound waves and ocean waves. Electromagnetic waves, on the other hand, are waves that do not need to travel through a medium. They are disturbances in both the electric and magnetic fields.…

of steel has more surface particles working to conduct heat. The thicker pieces of steel will take longer to heat up as when the boiling water touches the steel, the faster-moving particles of the hot water collide with the slower moving particles of the steel. The faster particles give up some of their heat energy to the slower particles as they collide. The slower particles gain more energy and collide with other particles in the steel. This process continues until heat energy is transferred…

SPRAY FOAM BASEMENT INSULATION: TORONTO Introduction Spray Foam Insulation (SFI,) also known as Polyurethane foam, is a very common practice among homeowners in the United States, UK, Canada, Australia, and some other countries. SFI is a heat-induced polymer – a spray-applied plastic with specially designed equipments capable of forming continuous insulation and serving as sealing barrier on walls, round corners, roofs, floor or ceiling cavity, as the case may be. It is produced by the mixture…

foods, and 2000 calories worth of healthy food, they both contain the same raw energy. If that's true, then why should you select the healthy option? That’s where nutrients come into play. Nutrients come in six parts, carbohydrates, proteins, fats, vitamins, minerals, and water. The first three in the list are classified as macronutrients. That means we eat them in fairly large quantities, and they contain the energy (calories) we need to get us through our day. The other three are…

What is meant by the specific heat capacity of a substance? It is the amount of energy required to increase the temperature of one gram of a body by one Kelvin unit, expressed as J/K/g. The specific heat capacity also can be measured in J/K/Kg and J/K/mol. Substance Specific heat Capacity (J/K/g) Water 4.18 acetone 2.17 hexane 2.26 Compare the specific heat capacity of water with a range of other solvents. The table compares the heat capacities of water and two other solvents. Compare the…

important to give a brief introduction of the concept of energy to then fathom the topics of thermodynamics, entropy, and enthalpy, and their relation to biology. Energy is a seemingly intuitive…

nutritionists are not sure of the true origin of the Calorie or why it’s supposed to be capitalized. Traditionally, a Calorie is the amount of energy needed to heat one kilogram of water one degree Celsius. It appears it was first used in engineering and physics, and then found its way in nutrition. With respect to nutrition, it is used to measure the amount of energy food contains. Some historians believe that there is some controversy as to whom invented the Calorie. It appears that two…

cost and the time we spend during long space travel, stay in the cold, vacuum universe would let astronauts experience different kind of radiation. These radiation may be some ionized particles as electromagnetic waves traveling with high speed and energy. They could come from nearby stars or even from those that are light-years away. Some of them has higher permeability when they are transmitting in the vacuum. Astronauts’ over exposure to the radiation during the long-term space travel can…
