Calculate the heat energy required to increase the temperature of 3 kg of water by 20ºC. The specific heat capacity of water is 4200 J/ kg °C

Heat energy required = 252000J or 252KJ.

Explanation:

Given the following data;

Mass = 3kg

Temperature = 20ºC

Specific heat capacity of water = 4200 J/kg°C

To find the heat energy required;

Heat capacity is given by the formula;

Where;

Substituting into the equation, we have;

Q = 252000 Joules or 252 Kilojoules.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
