How much energy is needed to reduce water temperature from 15 degrees to 14 degrees?
1 calorie increases 1 gram of water by 1 degree celsius. 4.18 Joules are needed to increase the temperature of 1 gram of water by 1 degree celsius.
To reduce the 1 gram of water 1 degree celsius it would have to give off 1 calorie of energy.
To calculate the energy multiply the mass in grams of water by 4.18 and by the change in temperature. The energy = 4.18 x m x change in T. The answer is in Joules. If you are using calorie as the unit of energy, replace 4.18 J by 1 C.
Note that food is measured in kilocalories (Calories) not metric calories.
What else can I help you with?
What can reduce the amount of energy needed for a chemical reaction to take place?
adding a catalyst to the reaction
What are the most efficient heating options for a small apartment?
The most efficient heating options for a small apartment are electric heaters, programmable thermostats, and proper insulation. Electric heaters are energy-efficient and can be used to heat specific areas when needed. Programmable thermostats help regulate the temperature and reduce energy consumption. Proper insulation helps retain heat and prevent energy loss.
Is energy faster or slower when water changes from a gas to a solid?
To condense a subject you must reduce temperature. Reducing the temperature of a substance reduces the amount of heat that the object has, which means less thermal energy. Thermal energy is the energy of molecular motion, so when you reduce it, molecular motion slows.
When removing oil from a low pressure system the temperature should be 130 degrees f because?
At 130 degrees fahrenheit, oil will have a lower viscosity, making it easier to flow and be removed from the system. This temperature is sufficient to reduce the oil's resistance and facilitate draining without causing damage to the system components.
Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
What should my water heater be set at to ensure optimal performance and energy efficiency?
To ensure optimal performance and energy efficiency, set your water heater temperature to 120 degrees Fahrenheit. This temperature is recommended to prevent scalding and reduce energy consumption.
What is the recrystallisation temperature of tin?
The recrystallization temperature of tin is approximately 100 degrees Celsius. At this temperature, tin undergoes recrystallization, where new grains form to reduce the strain and energy that accumulated during deformation.
Is 150 degrees too hot for a water heater?
Yes, 150 degrees Fahrenheit is too hot for a water heater. The recommended temperature for a water heater is typically around 120 degrees Fahrenheit to prevent scalding and reduce energy consumption.
How does temperature control in air conditioning systems impact energy efficiency and comfort levels?
Temperature control in air conditioning systems impacts energy efficiency and comfort levels by regulating the amount of energy needed to maintain a desired temperature. Proper temperature control can help reduce energy consumption and costs, while also ensuring a comfortable indoor environment for occupants.
How can I save energy by turning off the thermostat when I am not at home?
Turning off the thermostat when you are not at home can save energy by reducing the amount of heating or cooling needed to maintain a comfortable temperature. This can help lower your energy bills and reduce your overall energy consumption.
What is the optimal temperature for an ice pack to effectively reduce swelling and inflammation?
The optimal temperature for an ice pack to effectively reduce swelling and inflammation is around 32 to 41 degrees Fahrenheit (0 to 5 degrees Celsius).
What washing machine setting is 30 degrees?
The 30 degrees setting on a washing machine refers to a wash cycle that operates at a temperature of 30 degrees Celsius (about 86 degrees Fahrenheit). This setting is typically used for delicate fabrics and lightly soiled clothes, as it helps to preserve colors and reduce the risk of shrinking. It's an energy-efficient option, as it requires less energy to heat water compared to higher temperature settings.
What are the benefits of using baseboard heaters with thermostat for controlling the temperature in a room?
Baseboard heaters with a thermostat offer precise temperature control, energy efficiency, and cost-effectiveness. They can maintain a comfortable temperature in a room, reduce energy consumption by only heating when needed, and help save money on heating bills.
Enzyme reduce the amount of blank needed to start a reaction?
activation energy
What is the temp for smaw welding arc?
We were taught that the arc temperature can exceed 5,000 degrees F. Amperage settings can increase or reduce this temperature.
What are the most efficient thermostat settings for optimal energy savings?
The most efficient thermostat settings for optimal energy savings are typically 68F in the winter and 78F in the summer. Adjusting the temperature by a few degrees when you are asleep or away from home can also help save energy and reduce costs.
What is the best temperature setting for a geyser?
The best temperature setting for a geyser is typically around 55 to 60 degrees Celsius (130 to 140 degrees Fahrenheit). This range provides sufficient hot water for most household needs while minimizing the risk of scalding. Additionally, maintaining this temperature can help improve energy efficiency and reduce wear on the geyser. It’s advisable to avoid settings above 60 degrees Celsius to ensure safety and comfort.
