From its physical properties to its chemical properties‚ there are a numerous amount of ways to identify Chromium. For example‚ Chromium can be identified by its high melting and boiling point of 1907 degrees Celsius and 2672 degrees Celsius. But that’s not the only thing that can help identify Chromium. The atomic mass of Chromium is 51.996 and is unique to Chromium only. The amount of energy levels and the amount of electrons on its outer shell is also unique and gives

What was most interesting is that this temperature was consistent regardless of pre-cooling‚ the rate of heat storage‚ and the degree of heat adaptation. In other words‚ it seemed that humans have this “off-switch” at 40 degrees celsius‚ irrespective of the external intervention. The only thing that changed was the time it took to get there – for example‚ a person who is well adapted to the heat is able to sweat more‚ lose more heat and therefore takes much longer to reach this limit

a hydrogen bomb explosion‚ whose center registers approximately 100 million degrees Celsius‚ moves through the air at about 300 meters per second. In contrast‚ cosmologists believe the Big Bang flung energy in all directions at the speed of light (300‚000‚000 meters per second‚ a hundred thousand times faster than the H-bomb) and estimate that the temperature of the entire universe was 1000 trillion degrees Celsius at just a tiny fraction of a second after the explosion. Even the cores of the hottest

Bouncing Balls Coursework P3 1. Work out the average bounce height and put results in a table. Draw graph of the drop height against bounces height label axis. 2. Looking at my data‚ it is evident that when the drop height is 200cm for instance the average bounce height is 67cm compared to a shorter drop height of 120cm which has a average bounce height of only 50cm. This shows that when the drop height is higher the bounce height is also higher. 3. My data is good as I ensured that it was

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

Cellular Respiration: Using the Vernier LabQuest to detect CO2 gas production in germinating peas DESIGN Research Question: What is the effect of temperature on CO2 gas production in germinating peas? Background: The process of cellular respiration‚ which provides energy for cell growth and development‚ is an important part of life in germinating seeds. It converts the chemical energy of glucose into ATP. As a germinating seed respires‚ CO2 is produced as a byproduct. Therefore‚ the amount
