Ocean Acidification SDI: Solubility of CO2 in different temperatures Aim: To observe the solubility of CO2 in different temperatures Hypothesis: We hypothesise that in cold water the level of co2 absorption will be greater than warm water which will mean the air space in the cylinder will be less compared to warm water. Independent: Type of water. Dependant: room temperature‚ amount of water‚ type‚ size and amount of tablet‚ amount of water in the basin. Materials: 250ml graduated

Boyle’s Law - Solutions 1) If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L‚ what will the new pressure inside the piston be? P1V1 = P2V2 (1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm 2) I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver‚ where the air pressure is 0.85 atm‚ what will the new volume of the balloon be? P1V1 = P2V2 (1.0 atm)(15 L) = (0.85 atm)(x) x = 18

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚

Aim: In this investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot

Investigation Into Temperature Sensors Introduction In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in‚ and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as possible

Heat and Temperature Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same‚ but they are not.” Heat and Temperature‚ para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place

AUTOMATIC TEMPERATURE CONTROLLED FAN H ere is a circuit through which the speed of a fan can be linearly controlled automatically‚ depending on the room temperature. The circuit is highly efficient as it uses thyristors for power control. Alternatively‚ the same circuit can be used for automatic temperature controlled AC power control. In this circuit‚ the temperature sensor used is an NTC thermistor‚ i.e. one having a negative temperature coefficient. The value of thermistor resistance at
