How the surface area affects heat loss?
Heat loss of water: The surface area effects the the rate of heat loss because the rate of heat loss increases if the surface are is higher. How: The water is spread out into a bigger space meaning the
Which measures a bigger heat change 1c or 1f?
1C in 1.8 times as large a change.
Which measures a bigger heat change 1 degree C or 1 degree F?
1 degree C is a bigger change. It's 1.8 times the size of a change of 1 degree F. (Technically, these are changes in temperature, not heat. There's a difference.)
How does ice cool?
Water have a very high heat capacity and that mean water can contain a lot of heat which resulted in the cooling effect. Remember ice is water in solid form.
How much heat is required to change 0.2kg of ice at -5 degrees to water at 5 degrees?
Heat required for this transition is given as the the sum of three heatsheat required for heating the ice from -5 degree Celsius +latent heat(conversion of ice at zero degree to water at zero degrees)+heat required to heat the water from 0 to 5 degree CelsiusHeating of ice=m x s x delta T,where m is the mass ,s is the specific heat of ice=200x0.5x5=500calmelting of ice=mxlatent heat=200x80=16,000calHeating of water=m x s x delta T,where m is the mass ,s is the specific heat of water =200x1x5=1000calTotal heat required=500+16,000+1000=17,500 cal
