Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
If you dropped ice cubes in a pan and put it on a hot burner. when the water began to boil how many calories of heat energy had been absorbed by each gram of water in the pan?
1 calorie (or rather, kilocalorie). This is because the specific heat of water is 1.
What is the specific heat of a substance that has a mass of 25 grams and requires 525 calories to raise its temperature by 15 degrees celsius?
We know that Q=m.s.t, where Q= Heat, s= Specific heat of the substance, t=temperature(Difference in temperatures) =>s= Q/m.t =>s=525/(25X15) =>s=525/375 =>s=1.4 cal/g/0c Specific heat of the substance is 1.4 cal/g/0c.
What is the specific heat of a substance?
The amount of heat a substance can hold.
What is another term used for specific heat is?
Another term used for specific heat is temperature.
What is the relationship between specific heat and rate of heating?
change in temperature does not effect specific heat. for example,specific heat of water is 4.14 j/g.k at any temperature
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 quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C?

What substance is used as the standard against which you measure specific heats?
If you can measure 3 of these 4 things then you can use this formula q( energy in Joules ) = Mass * specific heat * temperature final - temperature initial
What is a substance that has a specific heat?
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
How many calories are required to raise the temperature of 105 grams of water from 30.0 degrees C to 70.0 degrees C?
q (amt of heat) = mass * specific heat * temp. differenceThe specific heat of water is 1.00 cal/goC & the temperature difference is 70-30 = 40oCq = (105 grams)*(1.00 cal/goC)*(40oC)= 4,200 calories
What error would be introduced into the value of J on failing to take into account the heat absorbed by the stirrer?
' J ' means Joules , unit for the amount of Energy in Physical Science... Heating Effect of Current ... Joule's Constant = Electrical Energy in Joules / Amount of Heat in calories Electrical Energy in Joules = Voltage in volts x Current in amperes x Time in seconds Amount of Heat in calories = Mass of Water x Specific Heat of Water x Change in Temperature of Water + Mass of Calorimeter x Specific Heat of Calorimeter x Change in Temperature of Calorimeter ANSWER: The Amount of Heat will be very hot and Joule's Constant will be too big which will make it not realistic as part of the experimental calculations. You must know that it is necessary to get the temperature in the state of equilibrium. Remember that, due to the use of the metal stirrer which absorbed the heat energy, the temperature of water inside the calorimeter had decreased partially or was delayed in rising up despite to the fact that the electrical energy generated is proportionally equal to the increase in temperature of the calorimeter.
If silver has a specific heat of about 0.06 calg degrees Celsius how many calories will it take to raise the temperature of a silver spoon that weighs 40 g from 20 to 88 degrees Celsius?
use the equation q=mc∆t, where q is the calories required, m is mass, c is specific heat capacity and ∆t is the change in temperature. Therefore... q=(40g)(0.06 cal/g◦c)(88c - 20c) q=163.2 calories
What is the specific heat of 40g of a substance if it requires 195.3 calories of energy to raise its temperature from 5 to 15 degrees Celsius?
488.25 J/kg/*C
If 1 gram of iron requires 0.11 calories to raise the temperature 1 degree Celsius what is iron's specific heat?
0.11cal/g degrees C
Do lipids need to be digested before they can be absorbed?
Yes- to be more specific they are "emulsified" by bile, before it is absorbed.
