- Suppose you have a sample that has a known density of 2.1 g/mL. If you have a mass of 0.34 kg of this substance, what is the volume in units of liters? Note: In your answer, do not include units. Type the numerical answer only or your answer will be counted as being incorrect.A microwave oven has a power requirement of 1,244W. A frozen dinner requires 5.8 minute to heat on full power. How much electrical energy in kWh is used ? If the cost of electricity is 17cents per kWh, how much does it cost to heat the dinner?The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?
