How much heat must be removed from 37.5 g of water at 90.0 C to cool it to 34.2 C?
The heat removed can be calculated using the formula: q = mcΔT, where q is heat, m is mass, c is specific heat capacity, and ΔT is the change in temperature. Given that the specific heat capacity of water is 4.18 J/g°C, you can calculate the heat removed by substituting the values into the formula.
What is the heat content of a gallon of water at a certain temperature?
The heat content of a gallon of water at a certain temperature can be calculated using the specific heat capacity of water (1 calorie/gram °C). For example, to calculate the heat content of a gallon of water at 20°C, you would need to know the mass of the water and apply the formula: heat content = mass of water x specific heat capacity x temperature change.
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.
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 has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
What is the dimensional formula of energy?
the formula to find specific heat is specific heat= calories/mass X change in temperature.
What is the formula to find Calories per gram?
(difference in water) x (mass of water) x (specific heat of water) x (1kc/ 10000c)
If the water reaches a maximum temperature of 26.4 degrees celsius how many joules of heat were released by the pebble?
To calculate the heat released by the pebble, we need to know the mass of the water and the specific heat capacity of water. Using the formula Q = mc∆T, where Q is the heat released, m is the mass of water, c is the specific heat capacity of water, and ∆T is the change in temperature (from initial temperature to 26.4°C), you can find the answer.
How do you work out specific heat capacity in physics?
To determine specific heat capacity in physics, you can use the formula Q = mcΔT, where Q represents heat transferred, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. By rearranging the formula to solve for c, you can find the specific heat capacity of the substance.
How To calculate Specific Heat of A compound Such as NaOH?
Specific heat is the measure of energy it takes to raise a unit mass in temperature by one degree Celsius. When measuring a compound that is water soluble, heat it separately to a specific range, then use the liquid to calculate the amount of heat that was used.
When 418 joules of heat energy are added to 10 grams of water at 20C the final temperature of the water will be?
To find the final temperature, we can use the formula: q = m x c x ΔT, where q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the temperature change. By rearranging the formula and substituting the values, we can find the final temperature to be approximately 39.8°C.
How many calories of heat is available when a hot water bottle containing 750g of water at 65 degrees cools to body temperature?
To calculate the calories of heat available when the water cools to body temperature, you need to consider the specific heat capacity of water. The specific heat capacity of water is 4.18 J/g°C. By using the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change, you can find the answer.
How much heat energy is tranferred to hot water?
The amount of heat energy transferred to hot water depends on various factors such as the initial and final temperatures of the water, the mass of the water, and the specific heat capacity of water. The formula to calculate heat energy transferred is: Q = mcΔT, where Q is the heat energy, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.
How can we calculate the heat lost by the hot water in a given system?
To calculate the heat lost by hot water in a system, you can use the formula Q mcT, where Q is the heat lost, m is the mass of the water, c is the specific heat capacity of water, and T is the change in temperature. This formula helps determine the amount of heat energy transferred from the hot water to the surroundings.
What is the amount of water that would change 15 degrees celsius when it absorbs 2646 joules of heat energy?
The specific heat capacity of water is 4.18 J/g°C. To find the mass of water that changes by 15°C when absorbing 2646 J of energy, you can use the formula: q = mcΔT (where q is the heat energy absorbed, m is the mass, c is the specific heat capacity, and ΔT is the temperature change). Rearranging the formula, you get m = q / (c * ΔT) = 2646 / (4.18 * 15) ≈ 42 grams of water.
What is the formula for heating water?
There isn't a "formula" for this. Or, at least, you haven't been specific enough for us to tell you what the governing formula is. Chemists usually indicate that heat is necessary for a chemical equation by putting a delta-H either over or under the reaction arrow (the meaning is the same either way).
How much heat energy is needed to convert 50 kg of water at 8 degrees Celsius to steam at 100 degrees Celsius?
The process involves increasing the temperature of water from 8°C to 100°C and then changing its phase to steam at 100°C. The total heat energy required can be calculated using the specific heat capacity of water and the heat of vaporization. The formula Q = mcΔT can be used to find the heat energy needed, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the temperature change.
