    In a solar water heater, energy from the Sun is gathered by water that circulates through tubes in a rooftop collector. The solar radiation enters the collector through a transparent cover and warms the water in the tubes; this water is pumped into a holding tank. Assume that the efficiency of the overall system is 29.0% (that is, 71% of the incident solar energy is lost from the system). What collector area is necessary to raise the temperature of 430...

    A small electric immersion heater is used to heat 57 g of water for a cup of instant coffee. The heater is labeled “190 watts” (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 24°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg·K.) How can I solve this problem?
