An immersion heater has a power rating of 600 watts. It is used to heat water for coffee. How long (in minutes) should it take to bring 1.1 L of water from room temperature (20°C) to 84°C?
An immersion heater has a power rating of 1200 watts. It is used to heat water for coffee. How long (in minutes) should it take to bring 1.3 L of water from room temperature (20°C) to 83°C?
An electric immersion heater has a power rating of 1800 W. If the heater is placed in a 1.2 kg of water at 25 °C, how many minutes will it take to bring the water to a boiling temperature? (Assume that there is no heat loss except to the water itself. cwater=4186 J/kg.°C)
An electric immersion heater has a power rating of 1200 W. If the heater is placed in a 1.6 kg of water at 15 °C, how many minutes will it take to bring the water to a boiling temperature? (Assume that there is no heat loss except to the water itself. cwater=4186 J/kg.°C)
A small electric immersion heater is used to heat 57 g of water for a cup of instant coffee. The heater is labeled "140 watts" (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 22°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg-K.) Number Units the tolerance is +/-2%
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?
4. An electric immersion heater normally takes 100 minutes to bring cold water in insulated container to a certain temperature, after which a thermostat swi heater off. One day the line voltage is reduced by 60% because of overload does the heating of water take now? Assume that the resistance of the heat does not change. switches th How long
A physics student uses a 115.00 V immersion heater to heat 330.00 grams of water for herbal tea. During the two minutes it takes the water to heat, the physics student becomes bored and decides to figure out the resistance of the heater. The student starts with the assumption that the water is initially at the temperature of the room Ti = 25.00°C and reaches Tf = 100.00°C.The specific heat of the water is c = 4180 J/(kg · °C)....
part b Review Constants Periodic Table An immersion heater used to boil water for a single cup of tea plugs into a 120 V outlet and is rated at 250 W. Suppose your super-size, super-insulated tea mug contains 400 g of water at a temperature of 13 °C. You can ignore the energy needed to raise the temperature of the mug and the heater itsell What is the resistance of the heater? Express your answer with the appropriate units. R=582...
37. A continuous flow water heater (geyser) has an electrical power rating 2 kW and efficienty of conversion of electrical power into heat-80%. If water is flowing through the device at the rate of 100 cc/sec, and the inlet temperature is 10°C, the outlet temperature will be (1) 12.2°C (3) 20°C (2) 13.8°C (4) 16.5°C
