The ideal temperature for brewing coffee is 200 Degrees Fahrenheit. That said, don't get overly concerned about hitting the exact right temperature. Drip brewers have their own thermostats, and some even offer you a choice of more than one brewing temperature.
You wish to heat water to make coffee. How much heat (in joules) must be used to raise the temperature of 0.180 kg of tap water (enough for one cup of coffee) from 19C to 96C (near the ideal brewing temperature)? Assume the speciï¬c heat is that of pure water, 4.18 J /(gC).
