- A 1000W electric kettle contains 1200g of water at 25*C. In how many minutes after the power is switched on is 200 g left in the kettle?If two +3.4 μC experience a force of 0.01 C/m, how far are they from one another?The answer is C) 205.36 but I am confused on the steps of how to solve this problem.
- A cup of water is heated with a heating coil that delivers 100 W of heat. In one minute, the temperature of the water rises by 20°C. What is the mass of the water?A. 72 g B. 140 gC. 720 g D. 1.4 kgAn aluminum rod is 20.0 cm long at 20°C and has a mass of 350 g. If 10 000 J of energy is added to the rod by heat, what is the change in length of the rod?The maximum flow rate of standard shower heads is about 3.5 gpm (13.3 L/min) and can be reduced to 2.75 gpm (10.5 L/min) by switching to low-flow shower heads that are equipped with flow controllers. Consider a family of four, with each person taking a 5-min shower every morning. City water at 15°C is heated to 55°C in an electric water heater and tempered to 42°C by cold water at the T-elbow of the shower before being routed to the shower heads. Assuming a constant specific heat of 4.18 kJ/kg·°C for water, determine (a) the ratio of the flow rates of the hot and cold water as they enter the T-elbow and (b) the amount of electricity that will be saved per year, in kWh, by replacing the standard shower heads by the low-flow ones.
- An aluminum rod is 20.0 cm long at 20.0°C and has a mass of 0.350 kg. If 1.00 x 104 J of energy is added to the rod by heat, what is the change in length of the rod?The pendulum in a grandfather clock is made of brass and keeps perfect time at 20 degrees C. if they is kept at 27 degrees C? (Assume the frequency dependence on length for a simple pendulum applies.) How much time is lost in a year?An electric coffeemaker has a 610-W heating element. The specific heat of water is 4.19 × 103 J/(kg⋅°C). How long, in seconds, does it take the coffeemaker to heat 0.76 L of water from 18°C to 88°C, assuming all the heat produced by the heating element goes into the water?
- An ice chest contains 3.49 kg of ice at 0 °C. Given a latent heat of fusion of water of 3.34 * 105 J/kg, how much energy (in J) must be added to the ice to completely melt it?A fixed mass of an ideal gas is heated from 50 to 80°C at a constant volume of (a) 1 m3 and (b) 3 m3. For which case do you think the energy required will be greater? Why?How long (in seconds) will it take to heat 40 kg of water from 40°C to 80°C with a 20-kW immersion heater? Assume no energy is lost to the environment and specific heat of water is 4.186 kJ/kg c
