- A diver 60 mm deep in 10∘C∘C fresh water exhales a 1.5 cmcm diameter bubble. What is the bubble's diameter just as it reaches the surface of the lake, where the water temperature is 20∘C∘C? Assume that the air bubble is always in thermal equilibrium with the surrounding water. Express your answer in centimeters.W/ solution please ty. An insulated calorimeter of mass 120g and of specific heat capacity of 0.22 cal/(g.C), contains 150g of water with a temperature of 20 A 200g metal ball at a temperature of 97 when added to the calorimeter causes the water reach a temperature of 27at thermal equilibrium. The specific heat capacity of water is 1.0 cal/(g.). What is the heat lost by the metal ball? What is the specific heat capacity of the metal ball?Please 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…
