Specific gravity What is specific gravity? Archimedes discovered that the weight of body in air minus its weight in water is equivalent to the weight of the water displaced by the body. Specific gravity is defined as "The weight of a body compared with the weight of an equal amount of pure water at 4°C (4°C is the temperature at which water is densest). When a body is placed in water‚ the volume of water displaced is equal to the volume of the body. When the body is placed in water that it

1 Honors Laboratory: Specific Heat and Conservation of Energy When energy in the form of heat Q is added to a material‚ the temperature of the material rises. Note that temperature‚ in units of degrees Celsius (°C) or Kelvin (K)‚ is a measure of how hot or cold a substance is‚ while heat‚ in units of joules (J) or calories (cal)‚ is a measure of its thermal energy. 1cal = 4.19J. A measure of the efficiency with which a substance can store this heat energy is known as specific heat capacity‚ or simply

Adhesion How does temperature change affect surface tension? As the temperature of a liquid increases‚ its surface tension decreases. When water heats up‚ the movement of its molecules disrupts the imbalanced forces on the surface of the water and weakens its sheet-like barrier of tightly bound molecules‚ thereby lowering the surface tension. This is why hot water is more effective when cleaning; its low surface tension allows it to more easily penetrate the fibers of a material like

How do people define fat? Or the basis to which people intake sugary beverages and the local authorities intervening for the benefit of public health? These are questions that each individual will answer differently in terms of their body fat and the amount of sugary beverages which they drink. In most cases‚ some people can not help but be addicted to sugary beverage because that is the substance that keep them mobile‚ but others will argue differently. In a similar way in which people will say

“What is the definition of health?” When I was first asked this question at the start of the semester‚ my initial thoughts jumped to a more direct answer that encompassed a person’s physical and mental health; observations of weight‚ musculature‚ neural defects‚ acumen‚ and mental clarity were some of the gauges I considered in determining a person’s measure of health. While I do not consider this definition wrong by any means‚ the defining of a person’s health should not cease on the surface level
