Students may convert temperature from Celsius to Fahrenheit and locate cities on wall map if Subject s:
I know from feedback that my gcse science summary revision pages have proved useful but they do not guarantee a high grade, that all depends on you and the factors mentioned in point 4.
Please note that my GCSE science revision pages are designed to be used for online convenience, so, beware, printouts could be quite long! Some quizzes, particularly the compilations, are quite large and take some time to download. Links to specific GCSE chemistry notes and quizzes about the topic in question have been added, and from these pages, you may find other links to more useful material linked to the topic.
In terms of old grades the following is an approximate comparison: Chemistry Paper 2 this page What's assessed in this paper? Chemistry Paper 4, Topic 13 "The rate and extent of chemical change" Appreciate that chemical reactions can occur at vastly different rates.
Whilst the reactivity of chemicals is a significant factor in how fast chemical reactions proceed, there are many variables that can be manipulated in order to speed them up or slow them down.
Chemical reactions may also be reversible and therefore the effect of different variables needs to be established in order to identify how to maximise the yield of desired product. Understanding energy changes that accompany chemical reactions is important for this process.
In industry, chemists and chemical engineers determine the effect of different variables on reaction rate and yield of product.
Whilst there may be compromises to be made, they carry out optimisation processes to ensure that enough product is produced within a sufficient time, and in an energy efficient way. Factors affecting the rate of a chemical reaction - temperature, concentration, particle size, catalysts etc.
Chemistry Paper 4, Topic 13 "The rate and extent of chemical change" 6. You should be able to: In the context of rates of reaction data, you must be able to Recognise and use expressions in decimal form. Use ratios, fractions and percentages. Make estimates of the results of simple calculations.
Translate information between graphical and numeric form. Plot two variables from experimental or other data. Determine the slope and intercept of a linear graph.
Draw and use the slope of a tangent to a curve as a measure of rate of change.Introduction. A trendline shows the trend in a data set and is typically associated with regression analysis.
Creating a trendline and calculating its coefficients allows for the quantitative analysis of the underlying data and the ability to both interpolate and extrapolate the data for forecast purposes.
I CAN write an equation in slope intercept form and graph the line using slope intercept form. HW: Worksheet Yes No Section I CAN write an equation in slope intercept form given the slope and a point on the line.
HW: Worksheet Yes No Section I CAN write an equation in slope intercept form given two points on . Write the slope-intercept form of the equation of each line. 1) 3 x − 2y = −16 2) Write the point-slope form of the equation of the line described.
17) through: (4, 2), parallel to Writing Linear Equations Date_____ Period____ Write the slope-intercept form of the equation of each line. Based on the point and the slope provided for each question, apply point-slope formula to find the equation of a line and express the equation in slope-intercept form: y = mx + c.
This level of worksheets features coordinates in the form of integers, and the slope provided can either be an integer or a fraction.
Simply knowing how to take a linear equation and graph it is only half of the battle. You should also be able to come up with the equation if you're given the right information.
