The specific heat of lead is 750kg degrees Celsius How much heat is needed to raise the temperature of a 500kg sample of lead by 50 degrees Celsius?
Multiplying: (spec.heat J.kg-1.K-1)*(masskg)*(temp.difference K or oC)= Heat needed (J)
128 (J.kg-1.K-1) * 500 (kg) * 50 (K) = 3.2*106 J = 3200 kJ
Special Notes:
J is Joule, SI unit for energy !!
Temp. difference in Kelvin (K) = same in degree Celsius (oC)
Spec. heat of Lead is 128 (J.kg-1.oC-1), not 750 !!
but of Potassium 750 (J.kg-1.oC-1)
What else can I help you with?
Does ice melt and boil at specific tempurtures?
Yes, ice melts at 0 degrees Celsius (32 degrees Fahrenheit) and boils at 100 degrees Celsius (212 degrees Fahrenheit at sea level). These are the specific temperatures at which the phase transitions occur for water.
How hot is a match?
Approx. 600 - 800 degrees C / 1,100 - 1,500 degrees F
The amount of heat energy required to raise the temperature of one gram of water by one degrees celsius is?
4.184 joules. The is the specific heat or Cp of water is 4.184 J/mol.
How much energy is needed to reduce water temperature from 15 degrees to 14 degrees?
1 calorie increases 1 gram of water by 1 degree celsius. 4.18 Joules are needed to increase the temperature of 1 gram of water by 1 degree celsius. To reduce the 1 gram of water 1 degree celsius it would have to give off 1 calorie of energy. To calculate the energy multiply the mass in grams of water by 4.18 and by the change in temperature. The energy = 4.18 x m x change in T. The answer is in Joules. If you are using calorie as the unit of energy, replace 4.18 J by 1 C. Note that food is measured in kilocalories (Calories) not metric calories.
How much heat energy is needed to convert 50 kg of water at 80 degrees Celsius to steam at 100 degrees Celsius?
539 calories per gram for heat of vaporization plus 1 cal/gram/degree C 100 degrees C - 80 degrees C = 20 degrees C (539 calories + 20 calories) X 50 kg X 1000 gm/kg = 27950000 cal = 27,950 kcal
What is the temperature of the region?
-21 degrees Celsius to 10 degrees Celsius.
Does ice melt and boil at specific tempurtures?
Yes, ice melts at 0 degrees Celsius (32 degrees Fahrenheit) and boils at 100 degrees Celsius (212 degrees Fahrenheit at sea level). These are the specific temperatures at which the phase transitions occur for water.
How many joules are needed to change the temperature of 100 g of water from 20 degrees Celsius to 40 degrees celsius?
8.200 J
What is the amount of energy needed to raise the temperature of 1 gram of water by 1 degrees Celsius?
The specific heat capacity of water is 4.18 Joules/gram degrees Celsius. Therefore, it would take 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
4 kg of ice at 0 degrees Celsius is converted to steam at 100 degrees Celsius How much heat is needed?
To convert 4 kg of ice at 0 degrees Celsius to steam at 100 degrees Celsius, you would need to calculate the heat required to raise the temperature of ice to 0 degrees Celsius, melt the ice to water at 0 degrees Celsius, raise the temperature of water to 100 degrees Celsius, and then convert water to steam at 100 degrees Celsius. The total amount of heat needed can be calculated using the specific heat capacities and latent heats of fusion and vaporization of water.
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 do you have if your temperature is forty degrees Celsius?
A fever. Normal body temperature is around 37 degrees Celsius, so 40 degrees Celsius would indicate a fever. It would be a good idea to monitor your symptoms and consult with a healthcare provider if needed.
Specific heat of air?
The specific heat of air at 0 degrees Celsius is 1.01 Joules per gram or J/g. The specific heat of a substance is defined as the quantity of heat per unit mass needed to raise its temperature by one degree Celsius.
What property of a material tells you how much energy it can store?
Specific heat capacity tells you how much stuff energy can store. specific heat capacity is the amount of energy needed to raise the temperature of 1kg of a substance by 1 degrees celsius. water has a specific heat capacity of 4200 J/kg degrees celsius.
If you wanted to know the the amount of heat needed to raise the temperature of 2 kg of steel by 10 degrees celsius what do you need to know about steel?
To calculate the amount of heat needed to raise the temperature of steel by 10 degrees Celsius, you would need to know the specific heat capacity of steel. This value represents how much heat is required to raise the temperature of a given mass of steel by 1 degree Celsius. Once you have this information, you can use the formula Q = mcΔT, where Q is the heat energy, m is the mass of the steel, c is the specific heat capacity, and ΔT is the temperature change.
How valid is the assumption that the initial temperature of the steam is 100 degrees celsius?
The assumption that the initial temperature of steam is 100 degrees Celsius is generally valid when referring to saturated steam at atmospheric pressure. However, it's important to consider that the temperature of steam can vary depending on the pressure or if it is superheated. Additional information or measurements may be needed to confirm the exact initial temperature of the steam in a specific scenario.
How hot is a match?
