Specific heat is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius, while calories are a unit of measurement for energy. Specific heat helps determine how much heat energy is needed to raise the temperature of a substance, while calories measure the amount of energy obtained from food or released during chemical reactions.

What is heat what and are units of heat energy called?
Heat is molecular motion; the units are BTU and calories.
What is the physics equation when finding the heat transfer in calories?
The equation for heat transfer in calories is given by Q = mcΔT, where Q is the heat transfer in calories, m is the mass of the substance in grams, c is the specific heat capacity of the substance in calories/gram°C, and ΔT is the change in temperature in degrees Celsius.
The amount of heat transferred to a system can be measured in?
The amount of heat transferred to a system can be measured in joules (J) or calories. Heat transfer is a form of energy transfer that occurs due to a temperature difference between the system and its surroundings. The specific heat capacity of a material determines how much energy is needed to raise its temperature by a certain amount.
What is energy expressed as heat?
Energy expressed as heat is the kinetic energy transferred between particles within a substance or between different substances due to a temperature difference. It is commonly measured in units such as joules or calories.
Does mercury has low specific heat?
No, mercury has a relatively high specific heat compared to other metals. Its specific heat is about 0.14 calories per gram per degree Celsius.

What is the specific heat of ice?
0.5 calories/gram

What is the formula to find Calories per gram?
(difference in water) x (mass of water) x (specific heat of water) x (1kc/ 10000c)
What is the difference between smaller specific heat and bigger specific heat?
A smaller specific heat capacity of a body means that a smaller amount of energy is required to raise the temperature of the body by 1 K compared to the other.
What is the dimensional formula of energy?
the formula to find specific heat is specific heat= calories/mass X change in temperature.

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

Energy expressed as heat is the kinetic energy transferred between particles within a substance or between different substances due to a temperature difference. It is commonly measured in units such as joules or calories.
Does mercury has low specific heat?
No, mercury has a relatively high specific heat compared to other metals. Its specific heat is about 0.14 calories per gram per degree Celsius.
What is the difference between carnot heat engine and a heat engine?
difference schematic diagram between carnot heat engine and heat engine
What is the difference between density and specific heat?
Density has dimensions of: mass/volume for example: the density of water at 4 °C is 1.000 g/cm3 Specific heat has dimensions of: energy/(mass·temperature) for example: the specific heat of water is about 1 calorie/g·°C
