Paragraph 1 Quartz-type iron phosphate‚ FePO4‚ exists in different phases at different temperatures. At low temperatures‚ it exists in the α-quartz-type phase‚ while at high temperatures‚ it exists in the β-quartz-type phase. The α-β phase transition occurs at 980K. In terms of lattice symmetry‚ α-FePO4 exhibits a trigonal lattice system‚ whereas β-FePO4 exhibits a hexagonal lattice system. In terms of space symmetry‚ α-FePO4 belongs to the P3121 space group‚ while β-FePO4 belongs to the P6422 space

this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess”

EFFECT OF ROOM TEMPERATURE ON THE BURN-RATE OF A CANDLE BURNS Have you ever wondered whether a candle burns more quickly on a hot day‚ than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C‚ 25°C and 30°C. Hypothesis A candle in a colder

The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

Research Report Introduction: The scientific principle that governs this kind of experiment was Combustion Reaction. It is a reaction that another element or compound reacts with oxygen to produce energy in the form of heat and light. It is a reaction that requires oxygen. My objective in doing this experiment is to determine the effect of the height of the candle on the length of its burning time. The existing problem is Suffocation. Research Problem: What is the effect of height of the candle on

Aim The aim of this experiment is to calculate the average human reaction time for a simple task. Hypothesis If the activity is repeated a number of times‚ then the reaction time will decrease‚ therefore the slower the reaction time‚ the further the ruler will fall. Variables - which variables are you going to: Change? (Independent Variable) The Independent Variable in this Investigation is the reaction time. Measure? (Dependent variable) The Dependent Variable in this Investigation is how

Introduction A rocket is a cylindrical projectile that can be boosted to a distinct height or distance by the combustion of its contents and is frequently utilised as a firework or signal. However‚ this term can also refer to a rocket engine. Similarly‚ to most engines‚ rockets burn fuel‚ which then turns into hot gas. The engine then pushes the gas out the rocket’s back‚ allowing the projectile to move forward. It is important to investigate how to successfully launch rockets to serve for different

According to the data‚ type B pencil had the highest resistance and type 11B pencil had the lowest resistance. B type pencils are darker than H type pencils. For B type pencils‚ the pencils get softer as its number increases. For example‚ a 6B pencil is softer than a 4B pencil. It was evident from the data that softer pencils have a lower resistance. For instance‚ the average resistance for a one centimeter line for a B type pencil was 0.275 MΩ‚ but for a 11B type pencil the average resistance decreased
