1. How to calculate Force?

An insulated bucket of negligible mass contains 1.75 kg of waterand 0.450 kg of ice. More ice, from a refrigerator at-15⁰C, is added to the mixture in the bucket, and whenthermal equilibrium has been reached, the total mass of icein the bucket is 0.778 kg. The latent heat of fusion of water is334 x 10³ J/Kg and the specific heat capacity of ice is2100 J/Kg.K. Assuming no heat exchange with thesurroundings, what mass of ice was added?

A 3.7 kg block of copper at a temperature of 70oC is dropped into a bucket containing a mixture of ice and water whose total mass is 1.2 kg. When thermal equilibrium is reached the temperature of the water is 8°C. How much ice was in the bucket before the copper block was placed in it?

A mass of 145 g of hot coffee at 85.0 oC is poured into an insulated cup containing 240 g of ice initially at 0.0 oC. After some time the system reaches thermal equilibrium.How many grams of liquid will there be then? How much ice ( in g) will remain?Thanks in advance! This is the only homework problem I am unable to solve!

What is an up or down angling of the camera while shooting?

0.12 kg of water at83.0^o C is poured into an insulatedcup containing 0.234kg of ice initally at 0^o. Calculatethe mass of liquidwhen the system reaches thermal equilibrium.

20. If you put a warm bottle of wine in a container of ice water,the wine will cool but the ice water won’t become warmer. Where isthe wine’s thermal energy going?


ANSWER FOUND ONLINE: The wine’s thermal energy is providing thelatent heat of melting necessary to transform ice into water.
