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 Q mc and DeltaT c represents .?
In the equation Q = mcΔT, the variable c represents the specific heat capacity of the substance. The specific heat capacity is a value that indicates how much heat energy is required to raise the temperature of a unit mass of the substance by 1 degree Celsius. It is a characteristic property of the substance.
What variable represents thermal energy in the equation?
In equations, thermal energy is typically represented by the variable "Q". It is the amount of heat transferred to or from a system.
What s the correct equation rearranged to solve for specific heat?
The correct equation to solve for specific heat is q = mcΔT, where q represents heat energy, m is mass, c is specific heat capacity, and ΔT is the temperature change. Rearranging the equation to solve for specific heat, we get c = q / (mΔT).
What equation represents the energy it takes to heat a sunstance?
The equation that represents the energy required to heat a substance is Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
What variable represents thermal energy in the equation Q mc T?
variable c
What equation represents the energy it takes to heat a substance?
Q=mc∆T
In the equation Q mcΔT c represents .?
The specific heat of the substance being heated.
In the equation qmct c represents?
In the equation qmct, c represents the speed of light in a vacuum, which is approximately 3.00 x 10^8 m/s.
What variable represent specific heat?
The unit for the specific heat capacity is J/kg.K.
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.
