A 0.425 kg sample of tin initially at 92.7 °C is dropped into 0.141 kg of water. The initial temperature of the water is 15.7 °C. If the specific heat capacity of tin is 230 J/kg°C, what is the final equilibrium temperature of the tin-water mixture?​

Ibelieve the answer is b. dugout

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
