When a hot object touches a cool object the particles in the hot object cause the particles in the cool object to?
It causes it to vibrate which causes it to heat up
Why do metals feel colder than wood when in same temperature and conditions?
Actually, the reasons metal objects often feel cooler than wooden objects has to do with the way the body feels heat and the rate metal conducts heat. If a room is left at 72 degrees Fahrenheit, all of the objects in the room will eventually reach 72 degrees, but a person standing in the same room will be at 98.6 degrees. When a person touches something in the room, he or she will be at a higher temperature than the object. Heat will flow from the hotter object (the wood or metal). The heat will flow through the wood or metal away from the person's skin, but at different rates, faster through the metal and slower through wood. We say then that metal conducts heat better than wood does. The end effect is there is less heat left in the finger where it touches metal than where it touches wood. The nerves in the finger sense the finger is cooler and the metal object seems cooler.
When a warmer object touches a cooler object what does heat move by?
if you mean to what way it transfer, always the heat is going to move to the cooler object. The means of heat transfer is conduction.
How does your finger tell whether or not an object is cold?
your finger can tell when an object is hot or clod because when a stimulus (the object) touches your skin, receptors transmit it to the brain and your brain sends a reflex reaction to let go
