TurpentineWhat is plastic behavior? object that comes back to its original size and shape when the load is no longer present O material deforms irreversibly, does not go back to its original shape and size when load is removed and stress vanishesA 3.87kg lead billet is to be melted for a casting operation. Lead has a melting point of 328°C, a specific heatcapacity of 128 J/(kg·K), and a latent heat of fusion of23,200 J/kg. (a)Calculate the amount of heat required to heat the lead from a starting temperature of 22.4°C to its melting point of 328°C. (b)Calculate the amount of heat needed tomelt the lead brick once it reaches 328°C.
- You shopping at the local grocery store and notice that tide laundry detergent costs $5.88 for 46 fl 0z and $12.10 for 90 fl 0z calculate and identify which is a better buyThe figure below, called a heating curve, represents the temperature of a block of ice as thermal energy is added. (The ice melts into water and then vaporizes into steam.) The thermal energy required to change phase from solid to liquid is calculated using the equation Q = mLf, where Lf is called the (latent) heat of fusion. The thermal energy required to change phase from liquid to gas is calculated using the equation Q = mLv, where Lv is called the (latent) heat of vaporization. cice = 2100 J/kg·K; cwater = 4186 J/kg·K; csteam = 2000 J/kg·K; Lf of water = 3.33 x 105 J/kg; Lv of water = 2.26 x 106 J/kgA snowball made of ice at -11.2 degrees Celsius is thrown at a brick wall. Assuming no energy is lost to the wall or surrounding air, how fast would the snowball have to be thrown in order to completely vaporize upon impact? Include units in your answer. More information.
