How do you convert mg into joules?
To convert milligrams (mg) to joules, you need to know the substance's specific heat capacity. The formula to convert mass in milligrams to energy in joules is Energy (Joules) = Mass (grams) x Specific heat capacity (J/g°C) x Temperature change (°C). So, once you have the specific heat capacity, you can use this formula to convert mg to joules.
How many joules of heat would be requiredto heat 0.5 kg of aluminum by 2k?
The specific heat capacity of aluminum is 900 J/kg·K. The amount of heat required can be calculated using the formula Q = mcΔT where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values, we get Q = 0.5 kg × 900 J/kg·K × 2 K = 900 J. Therefore, 900 joules of heat would be required to heat 0.5 kg of aluminum by 2K.
What is heat capacity temperature measured in?
The heat capacity of a substance is typically measured in units of energy per degree Celsius (Joules per degree Celsius, J/C) or energy per Kelvin (Joules per Kelvin, J/K).
What is the specific heat capacity of water and alcohol?
The specific heat capacity of water is approximately 4.18 J/g°C, while the specific heat capacity of alcohol (ethanol) is around 2.44 J/g°C. This means it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius, and 2.44 Joules for 1 gram of alcohol.
What is meant by Rupturing capacity of a circuit breaker?
lick
What is meant by joule's constant?
joules constant
What is the unit of measure for water?
Mass = kg Volume = liter (pints and gallons and also quarts in the USA) Heat Capacity - Joules per Kg per Kelvin etc Is that what you meant?
If you do 900 joules of work in 10 minuteshow much power have you used?
10 joules of work in 1 second
What is water's heat capacity?
It is 4.184 Joules/g/deg.
How much is done when an 45 N forces moves a block 20 m?
The work done would be 900 joules. Work is calculated by multiplying the force applied (45 N) by the distance over which it is applied (20 m). This gives the work done in joules.

What physical quantity is measured in units of joules?
Energy is measured in units of joules. It represents the capacity to do work and is used to quantify various forms of energy, such as mechanical, thermal, and potential energy.
Joules divided by Celsius times grams?
This calculation is used to find the specific heat capacity of a substance. The specific heat capacity is a measure of how much energy is needed to raise the temperature of a given amount of a substance by 1 degree Celsius. The formula used is: specific heat capacity = energy (in Joules) / (mass (in grams) * change in temperature (in Celsius)).
What is the specific heat capacity of saltwater?
63.9 ml per joules a second. In the arctic sea only.
What are the units of heat?
The Specific Heat Capacity of water is 4,184 Joules per kg per Kelvin

By what quantity must the heat capacity of an object be divided to obtain the specific heat of that material?
The heat capacity of an object must be divided by its mass to obtain the specific heat capacity of that material. The specific heat capacity is an intensive property that is independent of the size or amount of the material.
