The amount of heat gained or lost by a substance is equal to the product of?
mass times the temperature change rimes specific heat capactiy
How many times a solution of pH equals 3 be diluted to get a solution of pH equals 6?
The solution must be diluted 1000 times to get from a pH of 3 to a pH of 6.
Constant-pressure calorimeters can be calibrated by electrical heating When a calorimeter containing 125 mL of water is supplied with 4690 J of electrical energy its temperature rises from 21.4oC to?
First, calculate the water's mass by multiplying its density with volume. Next divide the energy supplied with (massXwater's specific heat) to find the rise in temperature. Add the result to the initial temperature to get the final temperature
If the volume of a confined gas is expanded to four times the original volume while its temperature remains constant what change will be observed?
The pressure of the gas will decrease by a factor of four when the volume is expanded to four times its original volume at a constant temperature, according to Boyle's Law.
What is the melting temperature of epoxy resin?
Specific heat capacity of epoxy resin depends on chemical structure of epoxy resin and range of temperature of measurements. Usually at 25 deg.C specific heat capacity of epoxy resins is 0.8-1.2 kJ/(kg*K). The specific capacity is growing with temperature, roughly increasing 1.5 times by 100 deg.C.
The amount of heat gained or lost by a substance is equal to the product of?
mass times the temperature change rimes specific heat capactiy
Suppose you want to heat 40g of water by 20 degrees Celsius how many joules of heat are required?
Use the equation q=mc(delta t) (that is, heat equals mass times specific heat times the change in temperature) to answer the question. The specific heat of water is 4.186 Joules per gram-Celsius. Therefore, q=(40)(4.186)(20), which equals 3348.8 Joules of heat (or approximately 3.35 kiloJoules of heat).
What times 31?
To find what times 31 equals a specific number, you can divide that number by 31. For example, if you're looking for what times 31 equals 93, you would calculate 93 ÷ 31, which equals 3. Therefore, 3 times 31 equals 93. If you have a specific number in mind, please provide it for a more precise answer!
The heat lost by the boiling water is equal to the heat gained by the room-temperature water How much heat was transferred in this process?
For this part you would use the formula Q equals mcT. Q is energy in joules, m is for mass of the water that is in grams, c is the heat of water, and T is the temperature change. Q is equal to 25,000 g times in parenthesis 4.186J divided by g times c closed parenthesis times open parenthesis 37 minus 25 C which equals 1255800 J or 1255.8 kJ.
What times what equals 13800?
The answer can not be specific if your question isn't. A possible answer is 138x100.
How many times does the temperature change a day?
2-3 times a day
How do Cooking times change due to temperature?
because if you are a certain temperature you dont want to cook.
What does the amout of force times the time applied equal?
It is the impulse which equals the change in momentum.
To determine the specific heat capacity of a solid conclusion?
To determine the specific heat capacity of a solid, conduct an experiment where you measure the temperature change of a known mass of the solid when a known amount of heat is added or removed. By calculating the specific heat capacity 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 determine the specific heat capacity of the solid. Repeat the experiment multiple times to ensure accuracy and reliability in your conclusion.
Calculate the specific heat of a substance if 44.0 g of the sample absorbs 67.2 J and the temperature change is 11 K?
The specific heat can be calculated using the formula: ( q = mc\Delta T ), where ( q ) is the heat absorbed, ( m ) is the mass, ( c ) is the specific heat, and ( \Delta T ) is the temperature change. Plugging in the values: ( 67.2 = (44.0) \times c \times 11 ), solving for ( c ) gives a specific heat of approximately 0.138 J/g∙K.
