Does a dishwasher use hot water or does it heat up the water put into it?
They use hot water and if it is not hot enough, the heating element used to dry the dishes will heat it to the right temperature.
A 48.26g sample of aluminum at 100.0C is dropped into 34.47g of water at 25.0C What is the final temperature?
To find the final temperature, you can use the principle of conservation of energy, Q lost = Q gained. The heat lost by the aluminum will be equal to the heat gained by the water. Use this formula: (mass of aluminum) x (specific heat capacity of aluminum) x (change in temperature) = (mass of water) x (specific heat capacity of water) x (change in temperature). You can then solve for the final temperature.
What does a calorimeter use the increase in water temperature for?
A calorimeter uses the increase in water temperature to calculate the amount of heat transferred in a chemical reaction or physical process. By measuring the temperature change of the water, the calorimeter can determine the amount of heat absorbed or released by the reaction.
Calculate the final temperature when 50 ml of water at 80?
When allowed to stand for long enough, the final temperature will reach room temperature.
How many joules of heat are needed to change the temp of 40 g of water?
To calculate the heat needed to change the temperature of water, you can use the specific heat capacity of water, which is 4.18 J/g°C. If you're specifying the temperature change, you would use the formula Q = m * c * ΔT, where Q is the heat energy, m is the mass of the water (40 g), c is the specific heat capacity of water, and ΔT is the temperature change.
How long does it take to heat water with oil fired centeral heating?
The time it takes to heat water with oil-fired central heating depends on factors such as the boiler's efficiency, the starting temperature of the water, and the desired temperature. Generally, it can take anywhere from 20 to 60 minutes for a boiler to heat water to a sufficient temperature for household use.
How do you calculate the heat capacity of a calorimeter containing water?
To calculate the heat capacity of a calorimeter containing water, you can use the formula Q mcT, where Q is the heat absorbed or released, m is the mass of water, c is the specific heat capacity of water, and T is the change in temperature. By measuring the temperature change when a known amount of heat is added or removed from the water in the calorimeter, you can determine the heat capacity of the calorimeter.
How much heat is required to raise the temperature of 0.25 kg of water from 20 Celsius to 30 Celsius?
The specific heat capacity of water is 4186 J/kg*C. To calculate the heat required, use the formula: heat = mass * specific heat capacity * change in temperature. Plugging in the values, the heat required to raise the temperature of 0.25 kg of water by 10 degrees Celsius is approximately 1046.5 Joules.
How much ice in grams would have to melt to lower the temperature of 53.0g of water from 65.0C to 0 C?
To lower the temperature of 53.0g of water from 65.0°C to 0°C, we need to calculate the heat required to cool the water and then use this heat to melt the ice. First, calculate the heat absorbed by the water using the formula: q = mcΔT, where q is the heat, m is the mass, c is the specific heat capacity of water, and ΔT is the temperature change. Then, use the heat absorbed to calculate the amount of ice melted using the heat of fusion of ice (334 J/g).
How long will it take to heat the water to 26 degrees?
The time it takes to heat water to a specific temperature depends on factors such as the initial temperature, the heat source, and the amount of water being heated. To get an estimate of the time needed, you could use a formula that takes into account these variables, such as the specific heat capacity of water and the power of your heating element.
Why heat is needed to boil water?
Because heat changes the temperature of the water
How much heat it take to raise the temperature of 645g of water by 25 c?
To calculate the amount of heat required to raise the temperature of water, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of water (645g), c is the specific heat capacity of water (4.184 J/g°C), and ΔT is the change in temperature (25°C). Plugging in these values, you will find the amount of heat needed in joules.
