In this experiment‚ I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction. I predict the higher the temperature‚ the faster the reaction rate. This is due to the kinetic theory. The more heat that is given to matter‚ the faster the particles move. This happens in the acid‚ so the faster the particles move‚ the faster the reaction rate due to more collisions between the marble chips and the

reason how different aspects of development affect one another and this is because the physical‚ social‚ emotional‚ intellectual all interlink with one another. If a child is less developed in reading‚ then when it comes to reading time as a group they may feel uncomfortable and not want to interact with anyone to form a friendship and this makes them feel slightly embarrassed and have low self-esteem. This them affects the child’s social and possibly language development. This then affects the child’s

The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

Sebastian is 6 years old and has just moved from Italy and has very poor English. He’s moved to a school where there are only children in the class with good level of English. Sebastian may be scared‚ confused and anxious about moving to another country with a different language. There will be a language barrier

Examine why time-space convergence occurs at different rates in various parts of the world. (15 marks) The basic concept of time-space convergence is when ‘the travel time required between places decreases and distance declines in significance’‚ and is used to examine the changing nature of spatial relationships. Time-space convergence occurs at different rates across the world‚ with some areas of the world having seen little in developments of technological links‚ or lacking available communications

Part I – Relation between BI rate and banks interest rate A. BI rate We take the BI rate‚ as the variable being estimated‚ from the period of 2006 until 2012. We then take the average rate in each year‚ rather than taking the rate in each month. As a note to the year 2012‚ we take the average rate that ranges only from January until August. Figure 1.

Reaction Rate Coursework Aim To see how the concentration of a reactant affects the rate of reaction‚ in this case sodium thiosulphate and acid. Scientific Background For a reaction to occur‚ the particles of the reactants must be colliding with each other with enough energy‚ the amount of energy needed for the reaction is called activation energy. Activation energy is altered by temperature‚ concentration‚ surface area of and the pressure on the reactants. Stirring the reactants also increases
