When you hold a cup of hot cocoa, your hands absorb the heat from the warm liquid through the cup. This increases the temperature of your hands, making them feel warm. Heat transfer occurs from the hot cocoa to your hands until they reach thermal equilibrium, balancing out the temperature difference.
Rubbing your hands together can generate heat from friction due to the molecules in your skin colliding and creating energy. This can help warm up your hands when they are cold.
When a liquid solidifies, it releases heat to the surroundings, making them feel warm. This is because the molecules in the liquid are reorganizing themselves into a more ordered structure in the solid state, which releases energy in the form of heat.
You can try rubbing your hands with a mixture of dish soap and warm water to help break down the cornstarch. Alternatively, rubbing your hands with a lemon slice can also help remove the cornstarch residue. Lastly, using a scrub or exfoliating soap can help to mechanically remove the cornstarch from your hands.
The disposable and portable product Hot Hands is used to keep hands warm in extreme conditions. These conditions are usually related to being in very cold climates where hands can get cold or develop frostbite.

Because the warm hot chocolate warms the cup and the cup warms your hands. also if you put your hands over the cup and feel the steam that will warm your hands.
When you rub your hands together, friction is created between them. This friction generates heat, causing your hands to feel warm.
because the cold energy is moving toward the warm energy and the cold is taking over.
As you warm up by the campfire, the heat causes the molecules in your hands to vibrate more rapidly. This increased molecular motion leads to the sensation of warmth that you feel. The heat energy from the fire is being transferred to your hands, causing the molecules in your skin to move faster.
When you exhale, the warm air from your lungs transfers heat to your hands, causing them to feel warm. This sensation occurs due to the body's natural heat transfer process and the difference in temperature between the exhaled air and your hands.
Your hands may feel warm due to increased blood flow to the area, which can be caused by physical activity, emotions like stress or excitement, or changes in temperature.
I think it's because of friction and because your hands are warm.

You've got it backwards. The superstition is "cold hands, warm heart" and it means that someone with cold hands is said to be a very "warm" or loving and generous person.
