As part of an experiment, a chemist measures the temperature of two solutions every minute.
\n" ); document.write( " At the beginning of the experiment, the sodium chloride solution’s temperature is 48 degrees higher than the potassium chloride solution’s temperature.
\n" ); document.write( " If the sodium chloride solution’s temperature increases by 1 degree per minute and the potassium chloride’s temperature increases by 7 degrees per minute, after how many minutes will the two solutions have the same temperature?
\n" ); document.write( ";
\n" ); document.write( "let m = no. of minutes of the experiment
\n" ); document.write( "let t = original temp of the potassium chloride
\n" ); document.write( "then
\n" ); document.write( "(t+48) = original temp of the sodium chloride
\n" ); document.write( ":
\n" ); document.write( "7m + t = m + t+48
\n" ); document.write( "7m - m = t - t + 48
\n" ); document.write( "6m = 48
\n" ); document.write( "m = 48/6
\n" ); document.write( "m = 8 minutes they will be the same temp
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, find the temp of each after 8 min
\n" ); document.write( "Sodium Chloride: 8 + t + 48 = t + 56
\n" ); document.write( "potassium Chloride: 7(8) + t = t + 56
\n" ); document.write( " \n" ); document.write( "
\n" );
