A
150degree Celcius piece of metal with a mass of 0.0342 kg gains
4.689 Kj of energy. determine the final temperature of the metal .
C metal : 0.385J(g. degree K)

Answer #1

The final temperature of the metal is 506.1 degree Celsius is 506.1 degree Celsius

1. A 74.20 kg piece of copper metal is heated from 21.5°C to
335.1°C. Calculate the heat absorbed (in kJ) by the metal.
2. A sheet of gold weighing 10.9 g and at a temperature of
17.3°C is placed flat on a sheet of iron weighing 23.9 g and at a
temperature of 52.2°C. What is the final temperature of the
combined metals? Assume that no heat is lost to the surroundings.
(Hint: The heat gained by the gold must...

Some ice at -15 degrees celcius with a mass of 0.45 kg is
dropped into a highly insulated cup (no heat flows into or out of
cup) with 3.0 kg water that is at 20 degrees celcius.
Determine if all the ice has melted
What if the final temperature of the water in the cup?

1- A piece of metal has a mass of 5.0 kg and a volume of 1000
cm3.
a) Find the density of the metal.
b) Would a 2000 cm3 piece of the same metal have the same
density?
c) What would the mass of the 2000 cm3 piece be?
2. Water expands when heated. If a beaker of water is heated
from 10 C to 90 C, does the pressure at
the bottom of the beaker increase, decrease, or stay...

A 187 g piece of metal
is rapidly removed from a furnace at a temperature of 600 °C and
quenched in 1600 g of water. The initial temperature of the water
is 25 °C.
If the final
temperature of both metal and water reach 33 °C and knowing that
the specific heat capacity of water is 4190 J kg-1
°C-1, calculate the specific heat capacity of the metal
in J kg-1 °C-1, (to 1 d.p.).
Answer: Answer J
kg-1 °C-1...

What is the mass of a piece of nickel metal if it is heated to
100.0C and placed into 250.0 grams of water at 21.52C in a
calorimeter with a heat capacity of 95.3J/K and the temperature
stabilizes at 25.82C

Calculate the specific heat of a metal (in calories/gram-degree
C) from the following data. A container made of the metal has a
mass of 3.80 kg and contains 13.1 kg of water. A 1.40 kg piece of
the same metal, initially at a temperature of 140 degrees C, is
placed in the water. The container and water initially have a
temperature of 15 degrees C, and the final temperature of the
entire system is 18 degrees C.

Calculate the specific heat of a metal (in calories/gram-degree
C) from the following data. A container made of the metal has a
mass of 3.20 kg and contains 13.1 kg of water. A 1.80 kg piece of
the same metal, initially at a temperature of 120 degrees C, is
placed in the water. The container and water initially have a
temperature of 15 degrees C, and the final temperature of the
entire system is 18 degrees C.

You
place 20g of ice initially at -10 degrees celcius and 200g of an
unknown substance initially at 90 degrees celcius together in an
insukated container. You find that the final temperature of the
system is 34.6 degrees celcius and note that the unknown substance
did not change phase. Given that the specific heat of ice is 2.04
kJ/kg•K, the specific heat of liquid water is 4.18 kJ/kg•K, and the
heat of fusion of water is 334 kJ/kg, find the...

A 5.10 kg piece of solid copper metal at an initial temperature
T is placed with 2.00 kg of ice that is initially at -25.0 ∘C. The
ice is in an insulated container of negligible mass and no heat is
exchanged with the surroundings. After thermal equilibrium is
reached, there is 0.90 kg of ice and 1.10 kg of liquid water.
Part A
What was the initial temperature of the piece of copper?
Express your answer to three significant figures...

A piece of titanium metal with a mass of 20.8 g is heated in
boiling water to 99.5 0C and then dropped into a coffee
cup calorimeter containing 75.0 g of water at 21.7
0C.When thermal equilibum is reached, the final
temperature is 14.30C.Calculate the specific heat
capacity of titanium. ( Specific Heat Capacity of H2O
(l) =4.184 J g-1 0C-1)
