For an object to melt, it needs to reach its melting point temperature, which is specific to the material. When heated to this temperature, the object's solid structure breaks down, allowing its particles to move freely and transition from a solid to a liquid state. Heat input is typically required to provide the necessary thermal energy for this process.

What is the amount of heat needed to melt 2 kg of ice?
The amount of heat needed to melt 2 kg of ice is 334,000 Joules. This value is known as the heat of fusion of ice, which is 334 kJ/kg.
How much enjergy is needed to melt 4.24 grams of Pd?
The energy required to melt a substance is its heat of fusion. For Palladium (Pd), the heat of fusion is 16.74 kJ/mol. To calculate the energy needed to melt 4.24 grams of Pd, first convert to moles by dividing by the molar mass of Pd (106.42 g/mol), then multiply by the heat of fusion. This yields approximately 3.34 kJ of energy needed to melt 4.24 grams of Pd.
How much energy is needed to melt 2kg of gold?
It takes approximately 64,000 Joules of energy to melt 1kg of gold. Therefore, to melt 2kg of gold, you would need around 128,000 Joules of energy.
When a hot object touches a cool object the particles in the hot object cause the particles in the cool object to?
transfer heat energy from the hot object to the cool object until they reach thermal equilibrium.
What fraction of the mass is needed to halt the object's motion?
To halt an object's motion, you need to apply a force equal to the object's mass multiplied by its acceleration. This means that the fraction of the object's mass needed to halt its motion is 1.
When a warm object is a brought near a cool object the cool object will?
it will do nothing except the ice will melt in your hand
A force needed to blank an object?
A force is needed to move an object.
Can inanimate objects melt ice?
inanimate object can melt ice quickly.ex microwave, furnace, flame thrower, ect

What is needed to melt a solid?
we need to melt a solid to convert it in liquid state and make some different and useful shapes or equipments.
The heat needed to melt one gram of a solid at its melting point is what?
The heat needed to melt one gram of a solid at its melting point depends on the heat of fusion value of the solid. To melt one gram of ice, for example, would require 334 J.
How much money is needed to start a factory?

Is needed to determine whether an object is in motion?
A Reference Point A reference point is needed to determine if an object is in motion.
What is needed to to facilitate diffusion and active transport?
ATP is needed for these two transport mechanisms to occur.
How many KWh are needed to melt steel?
The amount of energy needed to melt steel is approximately 1,650-1,800 kWh per metric ton, depending on the type of steel and the specific melting process used.
What is the amount of heat needed to melt 2 kg of ice?
The amount of heat needed to melt 2 kg of ice is 334,000 Joules. This value is known as the heat of fusion of ice, which is 334 kJ/kg.
