Hint: (T)2T.arrow_forwardPlease provide complete step by step answer: A customer orders 200ml of Sumatran coffee at precisely 60.0°C. You then need to drop the temperature of the coffee, initially at 90.0°C, to the ordered temperature. In order to simplify the calculations, you will start by assuming that coffee has the specific heat and density as if water. In the following parts, you will remove these simplifications. Solve now this problem assuming the density is 1.000 g/ml for coffee and its specific heat capacity is 4.184 J/(g ºC). If you had used ice cubes to cool the coffee, your calculation of q would have been a two- step process: (1) the ice at 0 oC first has to melt (energy added to go from solid to liquid; and then (2) to warm the liquid from 0 oC to the final temperature where q = mice cice + mwater cwater ∆T where cice = 2.11 J/ g . oC cwater = 4.184 J/ g . oC (Note: there is no ∆T for the first step since melting of the ice occurs at 0 oC, no temperature change) What…arrow_forwardProblem 1: How long does it take to heat a cup of coffee in a 1000-Watt microwave oven? This means that energy is used at the rate of 1000 Joules per second. Assume that the coffee starts at a normal room temperature of 25°C. Step 1: Guess an answer. Step 2: Estimate the volume of the coffee in mL and the final temperature that you want to attain. Step 3: Assume coffee has the same density and thermal properties of water. Find its heat capacity (specific heat times mass) in appropriate units. Step 4: Use the heat capacity and the desired temperature change to find the energy required. Step 5: Calculate the time required using the energy and the microwave power. Pay attention to units and use Power = Energy/time. Step 5: Is your answer reasonable?arrow_forward
