Background: As heat is a form of thermal energy‚ they tend to have the behavior of reaching a thermal equilibrium. This means that when two bodies of different temperatures come in contact with each other‚ the hotter ones will transfer heat particles to the body with a colder temperature‚ with an aim to reach this “thermal equilibrium”‚ whatever the temperature may be. The larger the surface area‚ means there can be more “paths” from the sides of the body that are capable of releasing this heat particles

liquid droplets with respect to heat capacity and droplet size Abstract Define Using Molecular dynamic simulation a cluster of particles was modelled and their behaviour analysed with respect to temperature change. As proof of a specific state i.e. solid‚ the Mean squared displacement was calculated and illustrated with respect to time. This occurred for varying temperatures. From the internal energy of the system per time step‚ the heat capacity was determined. Heat capacity was then plotted against

It therefor comes as no surprise that finding a way to make HTF’s more efficient is desirable

Why do darker colors absorb more heat than lighter Colors? Have you ever wondered why on a hot summer day you would be wearing a black or dark blue t-shirt and in like 5 min you’ll already be sweating and it would be really hot while your friends that are wearing white or yellow t-shirts are all ok and don’t seem affected by the heat. Have you ever thought what might cause this to happen? Well the color of our clothes is determined by a chemical dye that is added to the cloth at the factory

Oxygen (O) Human beings obtain this element from the air. It enters a person’s bloodstream through the lungs. The blood carries oxygen to the cells of the body. In the cells‚ oxygen combines with chemicals obtained from food. Energy produced during this process makes it possible for each cell to perform its function in the body. Also‚ oxygen atoms are present in water and water is essential to all life. It is present in many organic compounds. While oxygen is necessary for life‚ oxygen as ozone

To investigate the relationship between surface area : volume ratio and heat loss. INTRODUCTION: The aim of this experiment is to investigate and find the relationship between heat loss (of water) and surface area to volume ratio of animals. To investigate this‚ we are going to use three flasks of different volume (as the equivalent the animals) and thus different surface areas filled with water. BACKGROUND: Surface Area : Volume Ratios We will be using the following formula for calculating
