The specific heat of lead is 128 kg degrees Celsius How much heat is needed to raise the temperature of a 0.015kg sample of lead by 10 degrees Celsius?
The relevant equation behind this problem is Q=m*c* ΔT Where Q is the energy that must be added to or taken from the system, m is the mass of the object, c is the objects specific heat, and ΔT is the change in temperature in Celsius or Kelvin. Plugging in the given values we get that Q=.015kg * 128J/(kg*C) * 10C=19.2J. Therefore, you need 19.2 joules of heat in order to raise the temperature of a .015kg sample of lead by 10 degrees Celsius.
What is the specific heat of a substance that absorbs 2.5 x 10 joules of heat when a sample of 1.0 x 10 g of the substance increased in temperature from 10.0c to 70.0 degree c?
Q (heat) = mass*Specific Heat*Temperature differenceI assume 2.5 * 101 Joules? or 25 J & 10 grams of substance?25 J = 10 grams * (SH) * (70-10oC)25 J =10 g *60oC * SHSH = 25 J/(10 g * 60oC)S.H. = 0.0417 J/gOC
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
What does it mean to have a specific heat greater than water?
It means that it takes more energy to raise the object's temperature by 1 degree than it does to increase the temperature of water by 1 degree..
Is the heat an adverb?
No. It is a noun: "You've still got your soup on the heat."And a verb: "You still need to heat up your soup."But not an adverb; that modifies a verb, and adjective, or another adverb.
What variable represents specific heat in the equation Q mcT?
variable c
What variable represents specific heat in the equation Q equals mcT?
The variable c
In the equation qmct c represents?
c represents the "specific heat capacity" in which you will have to refer to the chart which lists the different elements' different heat capacities unless indicated by the question.
In the equation Q mcΔT c represents .?
The specific heat of the substance being heated.
In the equation Q mc and DeltaT c represents .?
Answer: Thermal Heat. Its Thermal somethingI just passed it and forgot the answer
What variable represent specific heat?
The unit for the specific heat capacity is J/kg.K.
What variable represents thermal energy in the equation Q mc T?
variable c
What does the specific heat of a substance represents?
The ability of a substance to hold heat.
What equation represents the energy it takes to heat a substance?
Q=mc∆T
Q equals m plus x t plus c In this equation what does Q t and c represent?
In the equation Q equals m plus x t plus c, Q represents the total quantity or value being measured or calculated. t represents the variable or time period being observed or measured. c represents the constant term or the y-intercept, which is the value of Q when t equals zero.
What s the correct equation rearranged to solve for specific heat?
That depends what the original equation is.
Why is the correct equation rearranged to solve for specific heat?
Probably because somebody wanted, precisely, to find the specific heat.
