A jet of steam at 100℃ is directed for a short time on to a large block of ice at 0℃. Some of the steam condenses to form water and some ice is melted. The condensed steam forms 0.40 kg of water at 0℃. Questions:

1. Calculate the heat given out by this steam in changing to water without change in temperature. [Take the specific latent heat of vaporization of water as 2 200 kJ/kg].

2. Calculate the heat given out by this water as it cools to the temperature of the ice. [Take the specific heat capacity of water to be 4.2 kJ/(kg K).]​

Mexico has a host of environmental problems, including significant chemicalpollution  from factory discharges and waste dumping, but the main threat to itsbiodiversity  probably stems from  deforestation  and other natural habitat losses. forest habitat is lost for a number of reasons

The reason why i feel that the theory of plate tectonics is correct because scientists have found dinosaur bones of the same species in africa, asia, and in the americas. which means that they must have been together at one point in time. plate tectonics is also how the hawaiian islands were formed. as the plate hawaii is on was moving north west, magma would melt through the sea bottom and hardening. forming into the island chain. plate tectonics also explains the mariana trench. two plates were moving away from each other and made a giant crack in the ocean floor running 2,550 kilometers (1,500 miles)  long.
