Heat gained by one object has to equal the heat lost by the other object. The final temperature of the two objects will be the same.
Object 1:
mass1 = 50 g
initial T1 = 20 oC
Cg = 2 J/degree/gram
final T1 = Tf
Change in temperature = Tf - T1
Q = Cg x change in T x mass
= 2 x ( Tf - T1 ) x 50
Water:
Mass = 200 g
Cg = 4.18 J/ degree/ gram
Change in T = Tf - 40
Q = 4.18 x (Tf - 40) x 200
4.18 x (Tf - 40) x 200 = -(2 x ( Tf - 20 ) x 50)
Tf = 37.9 oC

What does the specific heat of a substance relate to temperature change?
The specific heat of a substance is the amount of heat required to raise the temperature of one unit of mass of the substance by one degree Celsius. A substance with a high specific heat will require more heat to increase its temperature compared to a substance with a lower specific heat.
What are the 3 Measurements of Heat?
The three measurements of heat are temperature, specific heat capacity, and heat capacity. Temperature measures the average kinetic energy of particles in a substance, while specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Heat capacity is the total amount of heat required to raise the temperature of a substance by one degree Celsius.
What is the temperature at which a substance may exist in all three phases?
The temperature at which a substance may exist in all three phases (solid, liquid, and gas) simultaneously is known as the triple point. At the triple point, the substance's vapor pressure, temperature, and phase equilibrium are all in balance, allowing for coexistence of all phases.
What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C?
The quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius is defined as the specific heat capacity of that substance. It is measured in joules per gram degree Celsius (J/g°C) or in calories per gram degree Celsius (cal/g°C).
The amount of heat per unit mass required to raise the temperature by one degree Celsius is?
Specific heat capacity is the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree Celsius.
What does the specific heat of a substance relate to temperature change?
The specific heat of a substance is the amount of heat required to raise the temperature of one unit of mass of the substance by one degree Celsius. A substance with a high specific heat will require more heat to increase its temperature compared to a substance with a lower specific heat.
What is the heat required to change the temperature of 1 gram of a substance?
The heat required to change the temperature of 1 gram of a substance is known as the specific heat capacity of that substance. It is the amount of heat energy needed to raise the temperature of 1 gram of the substance by 1 degree Celsius.
How much heat is required to raise the temperature of the substance by 10 degrees Celsius?
The amount of heat needed to increase the temperature of a substance by 10 degrees Celsius depends on the specific heat capacity of the substance. This can be calculated using the formula Q mcT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature.
What is the density of 100 degrees Celsius?
The density of a substance at 100 degrees Celsius would depend on the specific substance. Generally, as temperature increases, the density of most substances decreases due to expansion of the material. It's best to look up the specific density of the substance at that temperature for an accurate value.
Is celsius in reference to heat?
Celsius is a unit of temperature measurement based on the Celsius scale, which is commonly used in many countries around the world. It is not specific to heat alone but can be used to measure the temperature of any substance or environment.
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
To raise the temperature of a substance, you need to calculate the heat energy using the specific heat capacity of the substance. Without knowing the specific heat capacity of the substance in question, it's not possible to determine the exact amount of energy required to raise the temperature from 30 to 45 degrees Celsius.
What are the 3 Measurements of Heat?
The three measurements of heat are temperature, specific heat capacity, and heat capacity. Temperature measures the average kinetic energy of particles in a substance, while specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Heat capacity is the total amount of heat required to raise the temperature of a substance by one degree Celsius.
Liquid changes into ice at what temperature?
Different depending on the specific substance, but water is 32 degrees Celsius.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What does heat capacity depend on?
Heat capacity depends on the substance's mass, the substance's specific heat capacity, and the temperature at which the substance is being heated. It is a measure of how much energy is required to raise the temperature of a substance by one degree Celsius.
What is the energy needed to change the temperature of 1kg of a substance by 1 degree C?
That depends entirely on the substance in question, but it is called the specific heat capacity. Energy = specific heat capacity x mass x change in temperature (Celsius or Kelvin) q = Cg x m x (T2 - T1)
What term describes the amount of thermal energy that is required to raise the temperature of a substance by 1.0 degrees Celsius?
Specific heat capacity is the term that describes the amount of thermal energy required to raise the temperature of a substance by 1.0 degree Celsius.
